CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The genotype is often written as YY or yy, for which each letter represents one of the two alleles in the genotype.

Detailed explanation-2: -Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles). The phenotype of this genotype is green seed color.

Detailed explanation-3: -An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).

Detailed explanation-4: -Genotype examples Let’s look at a classic example – eye color. A gene encodes eye color. In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father. The brown allele is dominant (B), and the blue allele is recessive (b).

Detailed explanation-5: -In our example, the possible genotypes are homozygous dominant (YY), heterozygous (Yy), and homozygous recessive (yy).
