WebNov 29, 2012 · If the allele is dominant, you write the allele as a capital letter. For example dominant allele for dark hair would be DD. You just do the opposite for recessive allels. Ex: … WebIn codominance, both alleles are completely expressed. If you crossed a red flower with a white one and the alleles were codominant, you might get flowers that are red and white in patches. If the alleles were incompletely dominant, the flowers would be pink because the … Each comes in two alleles, one of which makes pigment (the capital-letter allele) …

WebThe alleles can be shown as W for white and B for black. There are three possible genotypes : WW, BB and BW. There are also three possible phenotypes: WW = white, BB = black, and BW = speckled. WebAlleles may have superscripts (w a) or subscripts (A 1) or both. In teaching examples, alleles are often designated by capital and lower cases pairs (A & a; B &b). In dealing with eukaryotic, diploid organisms, the genotype for each autosomal gene is designed by a pair of alleles. Thus, the A gene might have genotypes AA, Aa or aa. WebAlleles may be either dominant or recessive: A dominant allele is always expressed, even if one copy is present. Dominant alleles are represented by a capital letter, for example, A.
