![]() ![]() The formation of a third phenotype specifically with traits that results from the combination of parent alleles is known as incomplete dominance or.The intermediate trait appearance in between the phenotypes of homozygous traits in the heterozygote is called incomplete dominance.For example, the pink color of flowers (such as snapdragons or four o’clock flowers), the shape of hairs, hand sizes, voice pitch in humans. The incomplete dominance is referred to as the dilution of the dominant allele with respect to the recessive allele, resulting in a new heterozygous phenotype.Incomplete dominance is defined differently as follows: ![]() Punnett square shows all the possible traits (genotypes) of the new offspring in graphical or table form after the crossing of homozygotes. The genotypic ratio is better understood through the Punnett square. The number of times of trait appearance in the offspring after crossing the genes or alleles of the specific trait identified through the genotypic ratio.Phenotype is determined by the genotype and refers to the organism’s appearance, characteristics, behavior, and development (physically observable features). A set of genes in an organism that is inherited by the offspring and that determines the offspring’s observable physical features is called the genotype.An organism that possesses two different alleles for a specific gene is described as heterozygous. An organism that possesses two same alleles for a specific gene and can truly breed for the allele is described as homozygous.Multiple alleles refer to the various alleles (two or more) for the same gene. The effect of an allele that is suppressed by the dominant allele and does not appear in the offspring is referred to as a recessive allele. The allele that masks or suppresses other alleles and becomes prominent in the offspring is called a dominant allele. An organism consists of two alleles from each parent for one gene. ![]()
