Explain why it is expected that heterozygotes will be produced twice as frequently as either homozygote in a monohybrid F1 cross

What will be an ideal response?


Combinatorials. Each individual offspring genotype has an equal likelihood of occurring (= ), but since there are two ways to make heterozygotes (Aa and aA), together they occur with a + = frequency, twice that of either homozygote, which occur at a frequency of each.
