Question

A snapdragon population consisting of 1000 sexually mature monecious plants exhibits random mating and the red allele is more common in the population. An incomplete dominant trait determines flower color. Red and white are homozygous and pink is heterozygous. If there are 480 pink plants, how many dominant red alleles are in the population?

Answer 1

P = frequency of dominant allele

Q = frequency of recessive allele

2pq = frequency of Heterozygous plants(pink)

P^{​​​​​​2} = frequency of Homozygous dominant plants(red)

Q^{​​​​​​2} = frequency of Homozygous recessive plants(white)

Hope that helps :)

Look forward to helping again.

Thank you!
