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:

What will be the genotype of the offspring if you cross a true breeding dominant red snapdragon (R) and a true breeding recessive white snapdragon (r)? Do the punnett square on a scratch paper. If flower color in snapdragons is an incomplete dominant trait, what will be the phenotype (color) of the offspring? Make sure to list the number of offspring with each genotype and phenotype (ie. Genotype= 1YY, 2Yy, 1yy Phenotype= 3 Yellow Flowers, 1 White Flower). Genotypes: Phenotypes:

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 is the probability of their offspring who will have freckles and no widow’s peak and no freckles and no widow’s peak? Freckles and No Widow’s Peak: No Freckles and No Widow’s Peak:

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:

In a mating between two individuals that are heterozygous for a recessive lethal allele that is expressed in the womb, what genotypic ratio (homozygous dominant:heterozygous:homozygous recessive) would you expect to observe in the offspring?
