Answer:
The correct answer is - Segregation
Step-by-step explanation:
An organism with the genotype Aa whose half of the reproductive cell or gametes carry A and the rest of the gametes or reproductive cell carries allele a. According to the laws of Mendel, it is the law of Segregation.
In a diploid organism, the genotype of an individual possesses a pair of alleles (50-50 %) for any particular character and is passed one of each to next-generation from each parent.
