Multiple Choice

You have brown eyes. This is known as a ______ trait

• Dominant

• Recessive

Multiple Choice

Independent Assortment states that genes can mix and match to create genetically different offspring

• True

• False

Multiple Choice

A child's parents both have blue eyes. Therefore, the child's alleles for eye color would be

• heterozygous

• homozygous

Multiple Choice

My alleles for eye color are Bb. This is an example of

• genotype

• phenotype

Multiple Choice

My eyes are brown. This is an example of

• Genotype

• Phenotype

Multiple Choice

Brown eyes are dominant (B). Blue eyes are recessive (b). If 2 siblings' genotypes are (BB) and (Bb), will they have the same eye color (phenotype)?

• Yes, because they have the same genotype

• Yes, because the dominant trait is always expressed

• No, because they have different genotypes

• No, because the recessive trait has to be expressed
