Question
In Mendelian inheritance, a gene has ______ allele(s).
Correct Answer
Option D is the correct answer.
Detailed Explanation
In Mendelian inheritance, for a given trait, an individual inherits two alleles, one from each parent. These alleles can be the same or different. However, a gene can exist in multiple forms (alleles) in a population, but an individual diploid organism carries at most two alleles for a single gene.
Hint
How many alleles for a single gene does a diploid individual inherit (one from each parent)?
