How many gametes does an individual with the AABbCc genotype form?
July 30, 2021 | education|
In a gamete there are 2 times less letters than in the genotype of an individual, that is, in our case, there are 3 letters in one gamete.
Each letter in the gamete occurs once, i.e. one letter A, one letter B, one letter C.
The number of gametes is in direct proportion to the number of heterozygous alleles in an individual. In our case, the AA genotype forms one type of gametes A, the other two heterozygotes Bb and Cc. Let’s compose gametes using the above definitions: ABC, ABc, AbC, Abc. Thus, an individual forms 4 types of gametes.
