Some alleles are dominant, meaning they ultimately determine the expression of a trait. Other alleles are recessive and are much less likely to be expressed. When a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic.
What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
Dec 20, 2023 · Dominant and recessive genes are two types of genes that determine the expression of traits in individuals. Dominant genes are those that overpower or mask the effect of recessive genes, while recessive genes only manifest their traits when paired with another recessive gene.
Capital letters represent dominant alleles and lowercase letters represent recessive alleles. The phenotypic ratios are the ratios of visible characteristics. The genotypic ratios are the ratios of gene combinations in the offspring, and these are not always distinguishable in the phenotypes.
Dominant traits are those that are expressed or observed when an individual has at least one copy of the dominant allele. These traits tend to be more common in a population and can mask the expression of recessive traits. On the other hand, recessive traits are only observed when an individual has two copies of the recessive allele.
