At a hypothetical locus, a man’s genotype is aa. what proportion of his gametes would be expectedto receive the a allele? a.1/3b.1/2c.3/4d.1/4e.1/8

The correct answer is 1/2

Explanation:

Based on Mendel's 2nd law - the law of independent assortment of genes - each character behaves as a separate unit and is INHERITED independently of any other character.

So, Aa will separate in two alleles "A" and "a". And by the law, each will be received by the gametes in equal rate of 50:50 i.e 1/2.

So for"A" allele, it is 1/2

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
