If Jessica has light eyes (bb) and both of her parents have dark eyes (Bb) which statement is true?

• Jessica inherited both genes from her father

• Jessica inherited both genes from her mother.

• jessica inherited one recessive form of the gene from each parent

• Jessica inherited one dominant form of the gene from each parent.

The arrow is pointing to a circled gentotype in the square. What genotype does the circled "dd" represent?

• the genotype in the mother's egg

• the genotype that only the girls will inherit

• the genotype that any of the children could possibly inherit

• the genotype that exactly ¹/₄ of the children will inherit

In pea plants , the allele for round seeds (R) is dominant to the allele for oval seeds (r). In a cross between two heterozygous plants, what percentage of the offspring will have round seeds?

• 100%

• 75%

• 50%

• 25%

In fruit flies, gray body color (G) is dominant over black body color(g). What kind of offspring would you expect from parents who are both heterozygous for body color (Gg x Gg)

• 0%gray, 100% black

• 25% gray, 75% black

• 75% gray, 25% black

• 100% gray, 0% black

In pigeons, the allele for normal feathers (F) is dominant to the allele for frizzy feathers (f). If a purebred, normal-feathered bird (FF) os crossed with a frizzy-feathered bird (ff), how many different feather phenotypes are possible in the offspring?

• 1

• 2

• 3

• 4
