Detailed explanation-1: -Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance.
Detailed explanation-2: -In contrast to recessively inherited traits, some alleles are dominant. With a dominant trait, an individual will express the associated phenotype even with just one copy of the allele for the trait.
Detailed explanation-3: -Refers to a trait that is expressed only when genotype is homozygous; a trait that tends to be masked by other inherited traits, yet persists in a population among heterozygous genotypes.
Detailed explanation-4: -Alleles produce phenotypes (or physical versions of a trait) that are either dominant or recessive. The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.
Detailed explanation-5: -The stronger of the 2 genes for a trait is called the dominant gene.
