Summary Introduction

To determine: The probabilities of the genotypes of the offspring.

Introduction: Gregor Johann Mendel, known as “Father of modern genetics”, was the first person to experiment on seven pairs of contrasting characters in pea plant. Based on these experiments, he proposed three laws namely “Law of dominance, “Law of segregation”, and “Law of independent assortment.” He stated that one or more pairs of alleles are responsible for each trait, and these alleles could be either dominant or recessive. Dominant alleles can be either in homozygous or heterozygous condition, whereas recessive alleles are expressed only in homozygous condition, as the dominant allele masks the expression of the recessive allele.
