<em>WOLVES, now returned to their original habitat, play a vital role in keeping the world of predator and prey in balance. Once they've eaten their fill, the leftovers from their kills provide food for scavengers, including bald and golden eagles, magpies, coyotes, ravens, and bears.</em>
In the given question,let say A is dominant allele and a is recessive allele
Homozygous recessive parent(having both alleles recessive) will be denoted by aa genotype whereas heterozygous parent(one allele is dominant while other is recessive) will be denoted by Aa
When a cross is made between both the parents then the probability of offspring having the recessive phenotype will be 1/2 or we can say 50%
