Answer Details

When gametes from pure breeding parents with contrasting features such as tallness and shortness are involved in monohybrid cross, the offspring in the first filial generation are usually heterozygous dominant. This means that the offspring inherit one allele for tallness (T) and one allele for shortness (t) from their parents, and the allele for tallness is dominant over the allele for shortness. As a result, the offspring exhibit the dominant trait of tallness, but they carry the recessive allele for shortness as well. This type of inheritance is known as Mendelian inheritance and follows the law of segregation, which states that each individual has two alleles for a particular trait, but only one is passed on to each offspring. The other allele is hidden or masked by the dominant allele.
