NEET BIOLOGY

Detailed explanation-1: -A dominant gene is represented by a capital letter. In an individual with genotype Tt, a capital letter or T will be the dominant allele. A pair of alleles that can control the height of an organism. Here, the allele represented with T is dominant.

Detailed explanation-2: -genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

Detailed explanation-3: -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.

Detailed explanation-4: -Heredity. In a Punnett square, capital letters represent dominant alleles. Lower case letters represent recessive alleles.

Detailed explanation-5: -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). Our genotype is our genetic code.
