Question

For a single-gene trait with alleles A and a, a certain mating produces offspring that are 1/4 AA : 1/2 Aa : 1/4 aa. What is the mating?

Answer 1

Random mating

Step-by-step explanation:

Random mating is a type of mating that allows individual to have equal chance of been mated to.

AA genotye is mated with aa from a population and they produce

Four individuals with Aa

AA × aa

!

F1: Aa Aa Aa Aa

This individuals then intermate in the next generation to produce an offspring with three difference genotype AA, Aa, aa in ratio 1:2:1 this is called segregation of genes. This allow to see the variation and hidden features of the individual mated.

Aa × Aa

!

AA Aa Aa aa

F2: 1/4 AA, 1/2 Aa, 1/4 aa
