What is the definition of 'homozygous'?

  1. Having different alleles for a trait

  2. Having identical alleles for a trait

  3. More than two alleles for one gene

  4. Genes carried by sex chromosome

The correct answer is: Having identical alleles for a trait

'Homozygous' refers to an individual having identical alleles for a specific gene or trait. This means that both alleles inherited from each parent are the same. In contrast, having different alleles for a trait, as in option A, is known as being heterozygous. Options C and D are incorrect as they do not accurately define 'homozygous.'
