Chromosomal theory of inheritance importance
WebThis is sex-linkage, or inheritance of genes that are on the sex chromosomes (X and Y). Sex-linked traits show interesting inheritance patterns in part because females have two copies of each X … WebGenetic Linkage and Distances. Mendel’s work suggested that traits are inherited independently of each other. Morgan identified a 1:1 correspondence between a segregating trait and the X chromosome, suggesting that random chromosome segregation was the physical basis of Mendel’s model. This also demonstrated that linked genes disrupt …
