NEET BIOLOGY

Detailed explanation-1: -Codominance. As opposed to partial dominance, codominance occurs when the phenotypes of both parents are simultaneously expressed in the same offspring organism.

Detailed explanation-2: -Genes can come in 2 different forms called alleles. We represent alleles with both lowercase and uppercase letters. Uppercase and lowercase letters are used to show which alleles are dominant and which are recessive. A dominant (uppercase letter) allele will overpower a recessive allele (lowercase letter).

Detailed explanation-3: -One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous ("homo” meaning “same") for that allele.

Detailed explanation-4: -Genetics is the scientific study of genes and heredity-of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence.
