NEET BIOLOGY

Detailed explanation-1: -In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed. The recessive trait won’t show, but you’re still a carrier. This means you can pass it on to your children.

Detailed explanation-2: -An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.

Detailed explanation-3: -Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote.

Detailed explanation-4: -The allele that is fully expressed in the phenotype of the heterozygote is called the dominant allele.

Detailed explanation-5: -One such example is the genetic inheritance of brown eyes, which is dominant, and blue eyes, which is recessive. If the alleles are heterozygous, the dominant allele would express itself over the recessive allele, resulting in brown eyes.
