Detailed explanation-1: -Dominant alleles represented by capital letter expresses itself in both, homozygous condition (AA, TT ) or heterozygous condition ( Aa, Tt ) in F1 generation.

Detailed explanation-2: -A dominant allele is denoted by a capital letter (A versus a). Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.

Detailed explanation-3: -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). phenotype = the physical appearance of a trait in an organism.

Detailed explanation-4: -Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Detailed explanation-5: -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.
