An organism having the genotype AaBbCcDdEe is self-fertilized. Assuming the five genes assort independently, determine the following proportions:

gametes that are expected to be ABcde

Key Concepts

Independent Assortment

Independent assortment is a fundamental principle of genetics stating that alleles for different genes segregate independently of one another during gamete formation. This means that the inheritance of one trait will not affect the inheritance of another, allowing for a variety of combinations in the offspring.

Gamete Formation

Gamete formation involves the process of meiosis, where diploid cells divide to produce haploid gametes. In the case of the genotype AaBbCcDdEe, each gene can contribute one of its two alleles to the gametes, leading to a diverse array of possible combinations based on the alleles present.

Probability in Genetics

Probability in genetics is used to predict the likelihood of certain genotypes or phenotypes occurring in offspring. By calculating the probability of each allele combination, one can determine the expected proportions of specific gametes, such as ABcde, from the self-fertilization of the organism with the given genotype.
