Class___
Show the cross and then answer the question for each problem.
(For your
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 RR x Rr 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 white, and heterozygous plants are pink. What
type of flowers will result in the F ( first
generation)of red and white? In the F2 ‘s (end
generation)?
red or
frizzle
4. In Poultry, a form of incomplete dominance is for the
trait” frizzle” F = frizzle N = no
and FN = slightly frizzled. If a frizzled male is crossed with
a non-frizzled female, what will be
the genotypes and phenotypes for the F generation? 1
