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.

R is dominant to r. Answer the following questions about this gene: What are the possible homozygous and heterozygous genotypes? The homozygous genotypes would be RR and rr, and the heterozygous genotype would be Rr. Which genotype or genotypes express the dominant R phenotype? Explain your answer.

Sep 17, 2023 · Because heterozygotes could arise from two different pathways (receiving one dominant and one recessive allele from either parent), and because heterozygotes and homozygous dominant individuals are phenotypically identical, the law supports Mendel’s observed 3:1 phenotypic ratio.
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.

Identify the correct genotypes for red, white, and speckled carnations. In some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors. Complete a cross between 2 speckled flowers and find the genotype ratio.
