1. Cattle can be red (RR = all red hairs), white (rr = all white hairs), or roan (Rr = red & white hairs together). Predict the phenotypic ratios of offspring when a white cow is crossed with a roan bull.

2. What should the genotypes & phenotypes for parent cattle if a farmer wanted only cattle with roan fur?​

plss answer,,now is the deadline

Sagot :

Answer:

1.

rr= white cow

Rr= roan bull

Parent: rr x Rr

Offspring: Rr, Rr, rr, rr

50% white

50% roan

2. If the farmer wanted only cattle with roan fur, he should cross a red cattle to a white cattle.

RR= red

rr= white

Parent: RR x rr

Offspring: Rr, Rr, Rr, Rr

Phenotype: 100% Roan
