answer use a different color, please)
1. In shorthorn cattle the gene for red coat color is not dominant over that for white coat color.
The heterozygous condition produces a roan color. A breeder has a white, red, and roan
cows and bulls. What phenotypes can be expected from the following crosses?
A. Red x roan
B. Red x red
C.. Roan x white
D. Red x white
2. A homozygous black chicken is crossed with a homozygous splashed white chicken ( white with black splashes same as the chicken in the video) and the resulting offspring are blue Andalusian chickens. Cross two heterozygous Andalusian chickens and give the results of their offspring.
3. In snapdragons, flower color shows incomplete dominance. Homozygous plants are red or white, and heterozygous plants are pink. What type of flowers will result in the F1 ( first generation)of red and white? In the F2 ‘s (end generation)?
4. In Poultry, a form of incomplete dominance is for the trait” frizzle” F = frizzle N = no frizzle and FN = slightly frizzled. If a frizzled male is crossed with a non-frizzled female, what will be the genotypes and phenotypes for the F1 generation?
In the F2 ‘s
