Answer:
0%
Step-by-step explanation:
Allele for white colour is represeted by w.
Allele for black colour is represented by b.
b allele is recessive to w allele.
Homozygous white rabbit will have the genotype ww.
Heterozygous white rabbit will have the genotype wb.
Crossing ww and wb:
ww x wb = ww, wb, ww, and wb
Since w is dominant over b, it means all of the offspring are white with 50% being homozygous and 50% being heterozygous.
The probability of a black rabbit offspring is 0%.
