Assume a phenotype is determined by one gene with a dominant allele and a recessive allele. If one parent is homozygous recessiv
e and the other is heterozygous, what is the probability that an offspring will have the recessive phenotype?
1 answer:
<h2>Phenotype probability</h2>
Explanation:
- 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%
