If you cross a white eyed female drosophila with a red eyed male drosophila, what will be the colour of eyes for their male and female offspring?

A farmer buys a black rooster (homozygous dominant) and a white hen (homozygous recessive) and crossed the two. To his surprise, when the first generation of eggs hatch all the chickens are black with white speckles throughout their feathers. What feather color(s) should the farmer expect after breeding two of the speckled chickens when their eggs hatch?

True or False: In flowers with codominant alleles for color, the flower color for heterozygous offspring will be a blending of the two colors. (ie red + white = pink).

On a scratch paper, do the dihybrid cross for a male that is homozygous dominant for freckles (freckles (F) is the dominant trait) and heterozygous for a widow’s peak (A widow’s peak (W) is the dominant trait) with a female who is heterozygous for freckles and homozygous recessive for a widow’s peak. What are the possible genotypes with phenotypes their offspring can have? Make sure to include the counts for each genotype (ie 2TTYY (Tall Plant with Yellow flowers). Genotype 1: Genotype 2: Genotype 3: Genotype 4:

True or False: In flowers with codominant alleles for color, the flower color for heterozygous offspring will be a blending of the two colors. (ie red + white = pink).

An individual with blood type O+ can donate blood to people with which blood types?

First comes love. Then comes marriage. Then comes baby in a baby carriage.  If the bride has blood type B (Bi) and the groom has blood type A (Ai), what possible blood types could their offspring have? Make sure to include your counts, genotype, and blood type. (ex. 1Bi (B blood type))

In purple people eaters, one horn (H) is dominant and no horns (h) is recessive. Complete the Punnett square to show the cross of two heterozygous purple people eaters.  Write the possible genotypes and phenotypes for the offspring (ie. Genotype= 1YY, 2Yy, 1yy Phenotype= 3 Yellow Flowers, 1 White Flower). Genotypes: Phenotypes:
