Which are the Two important themes that should be kept in mind as we follow the transmission of genes linked on the same chromosome?
Genes are known as the unit of heredity. Genes influence the outcome of organisms characteristics. These are the functional region present on the DNA. The alternative forms of genes are known as alleles. The alleles codes for the different versions of a particular inherited trait. Traits refer to the characteristics. The alleles can be either dominant or recessive. Dominant alleles are the alleles which hides the expression of recessive allele. A single dominant allele is enough to show the presence of a particular trait. A recessive allele is an allele which shows its effect only when present in its homozygous form.
