________________ is the study of how traits are passed on,or inherited

• dominant traits

• ratio

• phenotype

• genetics

An organisms's allele combination is known as

• phenotype

• hybrid

• mutation

• genotype

. An organism that has two identical alleles for a trait designated by two uppercase letters

• homozygous dominant

• heterozygous

• homozygous recessive

Who is the "father of genetics"?

• Gregor Mendel

• Oswald Avery

• Craig Venter

• Charles Darwin

Heterozygous is when...

• the alleles are present

• the alleles are absent

• the alleles are different

• the alleles are the same

One form of a gene is called_______________

• a DNA

• an allele

• a trait

• a Phenotype

bb crossed with BB, what is the probability of Bb?

• 25%

• 50%

• 100%

• 0%

An organism's appearance or other observable characteristics:

• dominant

• genotype

• recessive

• phentoype

Y= yellow pod

y= green pod

What is the percentage of yellow pod when you cross a hybrid pod plant with a purebred green pod plant?

• 100%

• 75%

• 50%

• 25%

The genotype is:

• the genetic makeup of an organism.

• the physical appearance of an organism.

• the deletion of a chromosome.

• the passing of traits from parent to offspring.
