What do we mean by homozygosity??? plzzz ans asap....
As the etymology of the word homozygous suggest homo means two of the same thing and zygous means genes. Hence, homozygous means having the same alleles at a particular gene locus on homologous chromosomes. Thus, homozygosity can be defined as the state of being homozygous (having two identical alleles of the same gene.) For example, a dwarf plant with genotype tt will be homozygous and this state is called the homozygosity.
Hope the answer helps,
