- Get the genotypic and phenotypic ratio of the following: Dihybrid cross: Harry has 1 pair of dog, he’s going to breed his Pure black, furry male to his white furless female (P generation). Also, he wants to find out what will be the result if he breed 2 offspring from F1 generation. Help him to predict the P and G ratio of F1 and F2 generation using the Punnett Square. Dominant Recessive Black White Furry Furless Trihybrid cross: Breed AaBbCc to another AaBbCc.Red/green colour blindness is a sex-linked trait. Show the Punnett square for a father who is colour blind and a mother who is not colour blind and not a carrier. What are the genotype and phenotype percentages of the possible offspring? Why do they say that such traits “skip a generation?”A monohybrid cross between two pea plants producing yellow peas, resulting in an F1 phenotypic ratio of 3:1 (three yellow pea plants to one green pea plant) indicates what about the parental pea plants? one parental pea plant is homozygous dominant, and the other is homozygous recessive both parental pea plants are homozygous dominant one parental pea plant is homozygous dominant, and the other is heterozygous both parental pea plants are heterozygous one parental pea plant is homozygous recessive, and the other is heterozygous
- The trait for red hair is recessive (r) to the trait for brown hair (R). What is the probability that two parents, one with red hair and one heterozygous for brown hair will have 6 children, 4 with brown hair and 2 with red hair?A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Identify the: Parents’ genes?Parents’ traits?Genes (genotype)?Shape, color? (phenotype)?Genotypic ratio?Phenotypic ratio?If homozygous recessive (aa,tetrapter) f1 produces homozygous (aa) f2, what is the dominant and recessive trait of f2? Let’s say the dominant trait of the parents of f1 is Wild type and the recessive trait is Tetrapter.
- Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.A man is homozygous dominant for fair skin and heterozygous for black-straight hair, his wife has brown skin and black-curly hair. The wife's hair color is the same genotypically with the husband. His mother in-law hair color is red since birth. The couple wanted to have kids. Is there a possibility that their child will have brown skin, curly-red hair, Yes or NO? If yes, what is its probability?In pea plants, yellow peas (Y) are dominant and green peas are recessive, smooth peas (S) are dominant and wrinkled peas are recessive. Create a Punnett square to show the cross of a homozygous recessive (for both) male and a heterozygous (for both) female. Give the probabilities of each genotype and phenotype.
- A man is homozygous dominant for fair skin and heterozygous for black-straight hair, his wife has brown skin and black-curly hair. The wife's hair color is the same genotypically with the husband. His mother in-law hair color is red since birth. The couple wanted to have kids. What is the probability that their child will be a girl?In cows, there is a "splotchy" phenotype that is splotches of brown and white. A true-breeding white cow (homozygous recessive) is bred to a true-breeding brown cow (homozygous dominant). In the resulting offspring, 75% have spots of brown and white and 25% are brown. The phenotype described displays what kind of relationship(s) between alleles?
