Chapter 13, Problem 1SQ
Summary Introduction
Concept introduction: The pair of chromosome where one of the pair is of maternal source and the other is of paternal source that has genes in the same loci with variable alleles of the gene is called as homologous chromosomes. Allele is the modification of the gene. Alleles are of two types namely dominant and recessive.
