if a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the offspring have?\no rw\no rw\no rw\no rw
Answer
Answer:
B. RW
Explanation:
Step1: Define alleles
Let R represent the allele for red (homozygous dominant red cow has RR) and W represent the allele for white (homozygous dominant white cow has WW).
Step2: Determine gametes
The red cow (RR) can only produce R - containing gametes, and the white cow (WW) can only produce W - containing gametes.
Step3: Find offspring alleles
When they are crossed, all offspring will have the genotype RW.
