Step 1 Introduction

Homozygous dominant : An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype . For example TT is tall and dominant and homozygous .

Heterozygous : Having two different alleles . It means they are inherited from each parent . In this situation dominant allele overrule the recessive one and therefore dominant trait will be expressed . For example : Tt Here T is dominant over t . t is recessive . So in Tt , T overrule the t so the phenotype will be tall and genotype is heterozygous .
