Phenotypic frequency calculator

WebIn drosophila, a recessive mutation (m-) of a maternal effect gene results in an abnormal phenotype wherein homozygous (m-m-) females produce eggs that cannot support embryonic development. Homozygous (m-m-) males, however, can still produce viable sperm. Using m+ to denote a normal gene, determine the genotypes and phenotypes of … WebFor a trihybrid cross, the F 2 phenotypic ratio is 27:9:9:9:3:3:3:1. The forked-line method can be used to analyze a trihybrid cross. Here, the probability for color in the F 2 generation occupies the top row (3 yellow:1 green).

WebThis provides a convenient method for calculating the expected genotypic and phenotypic ratios from a cross. A Punnett square is a matrix in which all of the possible gametes produced by one parent are listed along one axis, and the gametes from the other parent are listed along the other axis. WebThe proportion of heterozygotes (H) at a locus is a measure of genetic variation. For a locus with two alleles H o = f(Aa) = observed heterozygosity H e = 2pq = 2q(1-q) = 1 - q 2 expected heterozygosity. H e is the probability that two alleles chosen at random from the population will be different. For a locus with three alleles Since p + q + r = 1 The trinomial expansion …
