in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?

JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.
