I read in my book that "two alleles are considered to be homozygous if they are identical". But at the same time I read the definition of allele to be:
genes which code for a pair of contrasting traits are called alleles
My doubt is that how can they be both contrasting (different) and identical (same) at the same time
What I think is that if homozygous is somehow a part of specific conditions in alleles then how can it be different from alleles itself.
