Mr. Lloyd has been breeding tulip flowers for Valentines day. For the parent generation, he decides to cross a heterozygous dominant allele pair (red phenotype) with a homozygous recessive allele pair (white phenotype). What is the probability that the F1 - Generation offspring will be the color white? Remember, you must use the same letter of the alphabet, but has to be capital or lower case!

The probability that the F-1 Generation offspring will have recessive alleles (white phenotype) would be 50%

The probability that the F-1 Generation offspring will have recessive alleles (white phenotype) would be 25%

The probability that the F-1 Generation offspring will have recessive alleles (white phenotype) would be 75%

The probability that the F-1 Generation offspring will have recessive alleles (white phenotype) would be 100%

Dog breeders around the world want to breed certain traits within dogs. One dog, for instance, can have both the floppy ear genetic trait, and a straight ear genetic trait. Mrs. Lloyd is a dog breeder who knows that her dog has the floppy ears gene (tt), but wants all of her dogs future offspring to have straight ears. What type of genotype would the other dog have to have inherited for Mrs. Lloyd's dog to reproduce puppy's with the straight ear gene?

Mrs. Lloyd would have to breed her dog with a dog that has homozygous dominant gene trait. This means that if you cross a homozygous dominant allele pair and a homozygous recessive allele pair, the future offspring will have a 100 percent chance to have the straight ear gene.

Mrs. Lloyd would have to breed her dog with a dog that has heterozygous dominant gene trait. This means that if you cross a heterozygous dominant allele pair with a homozygous recessive allele pair, the future offspring will have a 100 percent chance to have the straight ear gene.

Mrs. Lloyd would have to breed her dog with a dog that has homozygous recessive gene trait. This means that if you cross a homozygous recessive allele pair and a homozygous recessive allele pair, the future offspring will have a 100 percent chance to have the straight ear gene.

The dog is unable to have straight eared puppies, but the puppies future offspring may be able to breed straight eared puppies.

What is the difference between genotype and phenotype?

phenotype is the detectable expression of the genotype. It is also an expressed or an observable trait, e.g. hair color. Genotype is the genetic makeup of an individual. Refers to the information contained on two alleles in the cell, e.g. TT, tt, Tt

genotype is detectable expression of the genotype. An expressed and observable trait. e.g. hair color. on the other hand, phenotype is The genetic makeup of an individual. Refers to the information contained on two alleles in the cell.

Hair color, eye color, weight, and the ability to roll one's tongue are examples of genotype. Phenotype is a section of DNA that may be susceptible to disease.

Gregor Mendel, the botanist scientist, was breeding pea plants to find out the genotypes and phenotypes of future offspring. He decided to breed two pea plants who's flower genetic makeup were both heterozygous dominant (Tt). The dominant allele was considered blue, while the recessive allele was considered to be green. Create a punnet square by crossing the two heterozygous dominant traits, and find out the F1 genotype offspring that the plants would create?

The F1 genotype offspring would consist of the following allele pairs: TT, Tt, Tt, tt

The F1 genotype offspring would consist of the following allele pairs: TT, TT, Tt, Tt

The F1 genotype offspring would consist of the following allele pairs: TT, tt, tt, Tt

Gregor Mendel, the botanist scientist, was breeding pea plants to find out the genotypes and phenotypes of future offspring. He decided to breed two pea plants who's flower genetic makeup were both heterozygous dominant (Tt). The dominant allele was considered blue, while the recessive allele was considered to be green. Create a punnet square chart by crossing the two heterozygous dominant traits, and find out the percent chance that the F1 would rather be blue flowers, or green flowers?

The ratio of the F1 flower offspring being the color blue would be 3/4, and the ratio of the green flowers would be 1/4.

The ratio of the F1 flower offspring being the color blue would be 2/4, and the ratio of the green flowers would be 2/4.

The ratio of the F1 flower offspring being the color blue would be 1/4, and the ratio of the green flowers would be 3/4.

All of the flowers would be blue in color, there would be no green flowers in the F1 offspring.

JURASSIC WORLD WAS A NEW ATTRACTION BUILD IN 2011, WITHIN WHICH WAS A HUGE SUCESS AT FIRST. PEOPLE AROUND THE WORLD WOULD COME SEE MANY DINOSAURS. ONE OF THE DINOSAURS PEOPLE WOULD LIKE TO SEE IS THE FIRST "HUMAN-MADE GENETIC HYBRID" THE INDOMINOUS REX. PROFESSOR LLOYD WAS TRYING TO IDENTIFY THE GENOTYPES OF THE PARENT OFFSPRING FOR TEETH TYPE. WHAT WOULD THE GENOTYPES OF TWO PARENT INDOMINOUS REX BE IF ONE HAD A GENOTYPE OF HETEROZYGOUS DOMINANT FOR TEETH TYPE, AND THE OTHER GENOTYPE WAS HOMOZYGOUS RECESSIVE FOR TEETH TYPE?

THE FIRST INDOMINOUS REX THAT HAD THE GENETIC MAKEUP OF THE HETEROZYGOUS DOMINANT TRAIT WOULD BE (Ee). ON THE OTHER HAND, THE GENETIC MAKEUP OF THE OTHER INDOMINOUS REX WOULD BE HOMOZYGOUS RECESSIVE (ee).

THE FIRST INDOMINOUS REX THAT HAD THE GENETIC MAKEUP OF THE HETEROZYGOUS DOMINANT TRAIT WOULD BE (Ee). ON THE OTHER HAND, THE GENETIC MAKEUP OF THE OTHER INDOMINOUS REX WOULD BE HOMOZYGOUS RECESSIVE (EE).

THE FIRST INDOMINOUS REX THAT HAD THE GENETIC MAKEUP OF THE HETEROZYGOUS DOMINANT TRAIT WOULD BE (EE). ON THE OTHER HAND, THE GENETIC MAKEUP OF THE OTHER INDOMINOUS REX WOULD BE HOMOZYGOUS RECESSIVE (ee).

THE FIRST INDOMINOUS REX THAT HAD THE GENETIC MAKEUP OF THE HETEROZYGOUS DOMINANT TRAIT WOULD BE (ee). ON THE OTHER HAND, THE GENETIC MAKEUP OF THE OTHER INDOMINOUS REX WOULD BE HOMOZYGOUS RECESSIVE (ee).

PROFESSOR LLOYD CONTINUED TO LOOK AT THE P1 GENERATION, AND WANTED TO IDENTIFY THE PHENOTYPES OF EACH PARENT FOR TEETH TYPE. WHAT WOULD BE THE PHENOTYPES OF EACH PARENT INDOMINOUS REX IF THE MALE PARENT DINOSAUR WAS HETEROZYGOUS DOMINANT FOR GENOTYPE, WHILE THE FEMALE INDOMINOUS REX PARENT WAS HOMOZYGOUS RECESSIVE FOR GENOTYPE?

THE PHENOTYPE OF THE INDOMINOUS REX WITH THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE SHARK TEETH. ON THE OTHER HAND, THE PHENOTYPE OF THE OTHER INDOMINOUS REX WITH THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE ELEPHANT TUSKS.

THE PHENOTYPE OF THE INDOMINOUS REX WITH THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE SHARK TEETH. ON THE OTHER HAND, THE PHENOTYPE OF THE OTHER INDOMINOUS REX WITH THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE SHARK TEETH.

THE PHENOTYPE OF THE INDOMINOUS REX WITH THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE ELEPHANT TUSKS. ON THE OTHER HAND, THE PHENOTYPE OF THE OTHER INDOMINOUS REX WITH THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE SHARK TEETH.

THE PHENOTYPE OF THE INDOMINOUS REX WITH THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE ELEPHANT TUSKS. ON THE OTHER HAND, THE PHENOTYPE OF THE OTHER INDOMINOUS REX WITH THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE ELEPHANT TUSKS.

MR. LLOYD DECIDED TO BREED THE P1 GENERATION OFFSPRING OF INDOMINOUS REX. THE MALE INDOMINOUS REX HAD A GENOTYPE OF HETEROZYGOUS DOMINANT FOR TEETH TYPE, WHILE THE FEMALE INDOMINOUS REX HAD A GENOTYPE OF HOMOZYGOUS RECESSIVE FOR TEETH TYPE. WHAT WOULD BE THE RESULT THE F1 OFFSPRING'S TEETH GENOTYPE RATIO? HINT, YOU HAVE TO CREATE A PUNNET SQUARE CHART, OR FOIL METHOD TO FIND THE F1 OFFSPRINGS TEETH GENOTYPE PERCENTAGE.

THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE 50 PERCENT. ON THE OTHER HAND, THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE 50 PERCENT.

THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE 25 PERCENT. ON THE OTHER HAND, THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE 50 PERCENT. THE FINAL DINO WOULD HAVE A 25 PERCENT CHANCE TO HAVE THE HOMOZYGOUS DOMINANT GENOTYPE.

THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE 50 PERCENT. ON THE OTHER HAND, THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE 25 PERCENT. THE FINAL DINO WOULD HAVE A 25 PERCENT CHANCE TO HAVE THE HOMOZYGOUS DOMINANT GENOTYPE.

THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HETEROZYGOUS DOMINANT WOULD BE 25 PERCENT. ON THE OTHER HAND, THE PERCENT CHANCE THAT THE F1 OFFSPRING WOULD HAVE THE GENOTYPE OF HOMOZYGOUS RECESSIVE WOULD BE 75 PERCENT.
