Step by step
Solved in 3 steps
- Draw a Punnett Square where one parent s a heterozygote and the other is a dominant homozygote; what is the probability of each possible genotype?If a phenotypic ratio for a single trait is 3:1 (75%:25%) in the offspring, whatgenotypes would you propose the parents might be? Draw a Punnett square to explain.In snapdragons, heterozygotes for one of the genes have pink flowers, whereas homozygotes have red (R) or white (r) flowers. When plants with red flowers are crossed with plants with white flowers, what proportion/probability of the offspring will have pink flowers? Create a Punnett square.
- Following a cross between two, dihybrid, heterozygous individuals, what fraction of the offspring are predicted to have a genotype that is heterozygous for both genes?what happens when two brown-eyed heterozygotes reproduce together?Build a Punnett square for a heterozygous browned eyed father and a heterozygous brown eyed mother while showing both Genotype and Phenotype ratiosIn a cross between fair skin, black hair (heterozygous for all these traits) with brown skin, red hair, what is the genotypic ratio of the offspring?
- If someone with auburn hair has children with someone with red hair (but whose mother had black hair), what are the genotype and phenotype probabilities for their children?If the A and the S alleles are co-dominant. What is the phenotype of a heterozygote (AS)?A cross between an orange-brown male and a homozygous black female produce four kittens. What is the phenotypic probability of the offspring? probability of the offspring?
- using a Punnett square, what will the offspring look like when the parents are Bb and Bb. B = dominant black hair and b = recessive blue hair. So what percentage of the offspring will have black hair vs blue hair?In a cross between BbTtSS and BBttSs, what is the probability of offspring being BBTtSS? Be specific on the answerIf body-color B is dominant to green body color b what would the genotype be for a heterozygous individual be? Using the blue B and a green b body color from above create a Punit square that represents the offspring of two heterozygous parents? what is the probability that they will have a child with a green body-color If the child is green what is its genotype? Cross a green parent with a homozygous blue parent. What color will their kids be?
