Practice objective / multiple choice question 38 from the 2024 Neco Biology examination.
In peas, two linked genes A/a (seed shape) and B/b (seed colour) have a recombination frequency of 10 %. The dominant alleles A and B give round yellow seeds, while recessive a and b give wrinkled green seeds. A plant heterozygous for both genes is in repulsion phase (AB on one chromosome, ab on the homolog). It is crossed with a homozygous recessive plant (aabb). What phenotypic ratio (in simplest integer form) is expected among the offspring?
