Chapter 4, Problem 8TYR
Summary Introduction
Introduction:
Homologous chromosomes carry two forms of a gene in the same locus is known as alleles. Usually one dominant (T) and one recessive (t) alleles are present and they produce different forms of a phenotypic trait. Dominant alleles are mostly responsible for the production of phenotypic traits because they mask the effect of the recessive allele. If individuals carry two identical alleles (TT or tt) of gene are known as homozygous and different types of alleles (Tt) of a gene is known as heterozygous.
