In a dihybrid cross of two bi-allelic Mendelian genes, A (two alleles – completely dominant A and recessive a), and B (two alleles – completely dominant B and recessive b), such that the parental generation comprises of pure-bred homozygotes (i.e. AABB with aabb), what are the expected genotype and phenotype ratios in the F1 and F2, if the F1 cross is (a) an intercross and if the F1 cross is (b) a testcross
1. A red-green colorblind woman marries a man with normal vision. What are the genotypes and phenotypes of the children? Identify the type of inheritance (complete dominance and if so which trait is dominant; or incomplete dominance or codominance/multiple alleles or sex linked, circle one) and define your symbols________________________________________________ a) What is the genotypic ratio of the above cross (Write number next to genotype)? b) What is the phenotypic ratio of the above cross? (Write number next to phenotype)?
Given a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: What proportion of the offspring will phenotypically resemble the first parent? What proportion of the offspring will genotypically resemble the second parent? How many phenotypes can be expected from the cross?
In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry. What is the phenotype of the male parent? What is the phenotype of the female parent? Give the phenotypic ratio expected among male children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio. Give the phenotypic ratio expected among female children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.
