What is Mendel's law of dominance?

According to Mendel’s Law of Dominance, “When an organism is heterogeneous for a trait, it expresses only the dominant allele”. In other words, the dominant trait always masks the recessive trait. What this means is that one allele is dominant over the other allele when they are different alleles.

What does dominance mean in biology?

In genetics, dominance pertains to the property of a gene (or allele) in relation to other genes or alleles. A gene or allele shows dominance when it suppresses the expression, or dominates the effects, of the recessive gene (or allele ). In ecology, dominance pertains to the high status of an organism or a group of organism in a social group.

What is incomplete dominance?

Incomplete dominance is a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype. It is also known as partial dominance. For eg., in roses, the allele for red colour is dominant over the allele for white colour.

What is apical dominance?

For example in plants, apical dominance refers to the condition in which vertical growth supersedes lateral growth. In biological contexts, it may mean differently in genetics, ecology, and neurobiology. In genetics, dominance pertains to the property of a gene (or allele) in relation to other genes or alleles.
