What determines the distribution of parental traits in the offspring?

The distribution of parental characters in the offspring depends on the distribution of parental chromosomes in meiosis and their subsequent paired combination in the zygote during fertilization. Sex chromosomes contain genes that determine not only sex, but also other characteristics of the body, which are called sex-linked. The transfer of genes located on the sex chromosomes and the inheritance of traits controlled by these genes is called sex-linked inheritance.
