Step by step
Solved in 2 steps
- 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.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?In pea plants, green color (G) is dominant to albino (g). If we cross two pea plants that are heterozygous for color, what would be the expected phenotype ratio of the offspring? Do the Punnett square and write the phenotypic ratio in the space below
- In the same cross as question #1, what fraction of the offspring will have their father's genotype for both traits?You cross a pea plant with the genotype AaBbCcDd with a pea plant that is AABbCCdd. What is the probability that you get an offspring with the genotype AaB_C_dd?In a cross between fair skin, black hair (heterozygous for all these traits) with brown skin, red hair, what is the phenotypic ratio of the offspring?
- You cross a pea plant with the genotype AaBbCcDd with a pea plant that is AABbCCdd. What is the probability that you get an offspring with the genotype AaB_C_dd? Show your workWhich of the following F2 phenotypic ratios show codominance? Assume you are starting with a parental cross of true-breeders and the F1 offspring is self-crossed. 3:1 2:1 1:1 1:2:1 1:1:1:1A heterozygous tall pea plant is crossed with a short pea plant. What are the expected genotypic and phenotypic ratios for this cross? ( you should write the genotype and phenotype for the generation)
- In certain plants, tall (T) is dominant to short (t). If a heterozygous plant is crossed with a homozygous short plant, what is the probability that the offspring will be short? Show the punnett square please.In a trihybrid cross involving three traits where the parents are AaBbCc. (a) What is the probability of them producing an offspring recessive for all three traits? (b) What is the probability of offspring with phenotype A_bbc_?In 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?
