NEET BIOLOGY

Detailed explanation-1: -Capital letters represent dominant alleles and lowercase letters represent recessive alleles.

Detailed explanation-2: -In Mendelian convention, a capital letter is used to denote the dominant allele of a gene and a small letter for the recessive allele of the gene. E.g. ‘Y’ is the dominant allele responsible for yellow seed coat while ‘y’ is the recessive allele responsible for green seed coat in pea plants.

Detailed explanation-3: -Dominant is always a capital letter and Recessive is always a lower-‐case letter. Here is where I write down the letters that represent my couple. Because they are heterozygous, I use one capital letter and one lower letter since they have both traits in their genes.

Detailed explanation-4: -Table 2: Examples of symbols used to represent genes and alleles. Uppercase letters represent dominant alleles and lowercase letters indicate recessive alleles.

Detailed explanation-5: -A capital letter represents the dominant allele and a lowercase letter represents the recessive allele. Alleles are all the forms of a gene for any given trait. There are usually two allele possibilities for every trait.
