 Males and females both contribute equally to the genotypes of their offspring, in which gametes fuse and form.An important aspect of the formation of the parent offspring is the chromosome, which is a structure of DNA which contains many genes.To focus more on the offspring and how it results in the formation of the f1 generation, is an inheritance called sex-linkage, which is a gene which is located on the sex chromosome and patterns of these inheritance differ in both male and female.
