Why do children look similar but not exactly like their parents?

Multiple Choice

What is Mendel's Law of Independent Assortment?

• If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

• The passing of allele of one trait does not affect the passing of allele of another trait.

• If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.

• If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

Multiple Choice

Mendel's Law of Segregation means?

• Every person has two alleles for each trait, they segregate from each other and the dominant is passed more often.

• Every person has two alleles for each trait, Where two traits are being passed, they do not effect each other.

• Every person has two alleles for each trait, they segregate from each other and are passed down at random.

• Every person has two alleles for each trait, they segregate from each other and the recessive is passed more often.

Multiple Choice

Abigail has a long-haired pet cat and James has a short-haired pet cat. When they bred their cats, the kittens had a medium-length coat. What does this represent?

• Incomplete dominance

• Codominance

• Complete dominance

Match

Match the law with the definition

• States that the alleles of two different genes get sorted into gametes separately of one another

• States that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic

• States that alleles for the same gene will separate into different gametes
