How many alleles (letters) are in the genotype for a simple trait?

How many alleles (letters X or Y) does a child get from EACH parent for each trait?

Who is considered the "father of genetics"?

What are the phenotype percentages of the offspring?

(A-Brown fur color; a-white fur color)

What ratio of the offspring from the cross shown will be homozygous recessive for the trait of tallness? 

If A = red fur and a = white fur, what color fur would aa be?

If A = red fur and a = white fur, what color fur would AA be?

If A = red fur and a = white fur, what color fur would Aa be?

If A = green pods and a = yellow pods, what are the GENOTYPIC RATIOS of the offspring in the Punnett square?

If A = green pods and a = yellow pods, what are the PHENOTYPIC RATIOS of the offspring in the Punnett square?

A homozygous brown mouse is crossed with a heterozygous brown mouse (tan is the recessive color).

Perform a punnett square cross and determine the phenotype & %.

What genotype would go in box 2? And is it Homozygous or Heterozygous?

What are the possible genotypes for this cross? And what percentage of each is produced?

A heterozygous tall pea plant (T) is crossed with a short pea plant (t).

Perform a punnett square cross and determine the Genotype & %.

Which of these Punnett squares represents a cross between a homozygous dominant parent and a heterozygous parent?

Based on this Punnett square, what is the chance that an offspring will have a homozygous genotype?

If both parents have the genotype Aa, what is the chance their offspring will also have the genotype Aa?

In pea plants, being tall is dominant and being short is recessive. Two tall plants mate. One has the genotype Tt and the other has the genotype TT. What is the chance that they will have a tall offspring?

In humans, being able to curl your tongue is a dominant trait and NOT being able to curl you tongue is a recessive trait. If a mom with the genotype Rr has a child with a dad with the genotype Rr, what is the probability that their child will be able to curl its tongue?

A dog with straight fur (Bb) is crossed with a dog with curly fur (bb). What is the probability the offspring will have straight fur?

In rabbits, black fur is dominant and white fur is recessive. If two white rabbits mate, what is the chance that they will produce an offspring with black fur?

SpongeBob is known for his big round eyes, which is dominant. Having oval eyes is recessive. If he is heterozygous and marries a woman with oval eyes, predict the chance of them having a baby sponge with oval eyes.

Having freckles is a dominant trait. Not having freckles is a recessive trait. A child is born and has NO freckles. The mother has freckles and the father does not have freckles. What is the genotype of the mother?

Cody crosses a plant producing wrinkled peas with a plant producing smooth peas. Weeks later, he discovers that all the offspring plants have smooth peas. Cody drew the Punnett square above to show the genotypes of the offspring plants. What were the genotypes of the parent plants?
