What are some important characteristics of dominance? - Dominance is an interaction between different alleles of a gene. Dominance does not alter the way in which genes are inherited; it only influences the way in which the genes are expressed.
The dominant/recessive character is a relationship between two alleles and must be determined by observation of the heterozygous phenotype. An example of a simple phenotype is the flower colour in Mendel’s peas.
Sep 17, 2023 · In a test cross, the dominant-expressing organism is crossed with an organism that is homozygous recessive for the same characteristic. If the dominant-expressing organism is a homozygote, then all F 1 offspring will be heterozygotes expressing the dominant trait (Figure \(\PageIndex{4}\)).
1 day ago · Dominant, as related to genetics, refers to the relationship between an observed trait and the two inherited versions of a gene related to that trait. Individuals inherit two versions of each gene, known as alleles, from each parent.
