You do a testcross to map three genes, Ph, T, and Qc. In the table below, you will find the number of offspring that inherited each combination of alleles from the heterozygous parent. Make a genetic map and then report the genetic distance between each pair of genes to the nearest 0.1 cM. Ph gene T gene Qc gene counts ph Qc 304 Ph qc 301 Ph T. qc 172 ph Qc 169 ph T. qc 21 Ph Qc 19 Ph Qc ph t qc 6 Genetic distance from Ph to T: cM Genetic distance from T to Qc: cM Genetic distance from Ph to Qc: cM

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
