Differentiate between homozygous and heterozygous.

(N/A) $1$. Homozygous: An individual is said to be homozygous for a trait if it possesses two identical alleles for that specific gene (e.g.,$TT$ or $tt$). These individuals are often referred to as true-breeding or pure-breeding lines.
$2$. Heterozygous: An individual is said to be heterozygous for a trait if it possesses two different alleles for that specific gene (e.g.,$Tt$). These individuals are often referred to as hybrids.
$3$. In summary,homozygous organisms produce gametes with identical alleles,whereas heterozygous organisms produce gametes with different alleles.
