Phenotype ratios
WebThe probabilities of different offspring genotypes and phenotypes can be determined using a Punnett square. A dihybrid cross results in a roughly 9:3:3:1 ratio of offspring phenotypes.

WebExpert Answer. Directions: Use the Punnett Square to determine the genotype and phenotype ratios of each cross. Show your work! In rabbits, gray hair (G) is dominant to white hair (g), and black eyes (B) are dominant to red eyes (b). To predict the probability of these sorts of crosses, we will make a dihybrid Punnett Square. WebA phenotype is an organism’s observable characteristics. For example, suppose a pea plant produced two different colored pea pods, green and yellow. These two colors represent …
WebMar 15, 2024 · The A-type group showed a significantly lower one-year acute exacerbation rate than the other two groups (P < 0.05). A relatively longer course of disease, a relatively lower forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) ratio and CT phenotype were correlated with the unfavorable prognosis of patients. WebThe phenotypic ratio is therefore 13:3. This type of epistasis is sometimes called dominant suppression, because the deviation from 9:3:3:1 is caused by a single allele that produces …
WebApr 9, 2024 · The four phenotypic classes correspond to the genotypes: A_B_, A_bb, aaB_, and aabb. If either of the singly homozygous recessive genotypes (i.e. A_bb or aaB_) has the same phenotype as the double homozygous recessive ( aabb ), then a 9:3:4 phenotypic ratio will be obtained. WebThe phenotype ratio predicted for dihybrid cross is 9:3:3:1. Of the sixteen possible allele combinations: Nine combinations produce offspring with both dominant phenotypes. …
