5.90 Genetics of peas. According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. (a) What is the probability that exactly 8 out of 10 of these plants have red blossoms? (b) What is the mean number of red-blossomed plants when 130 plants of this type are grown from seeds? (c) What is the probability of obtaining at least 90 red-blossomed plants when 130 plants are grown from seeds?

Genetics: According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white. Each plant has a probability of 3/4 of having red blossoms, and the blossom colors of separate plants are independent. You are testing 10 pea plants for their blossoming behavior. a. Explain why the event “having red blossom” in this specific context is binomial using the four characteristics of a binomial setting. b. What is the...

According to a genetic model, the distribution of fur color of the second generation Havana rabbit (Oryctolagus cuniculus) should be 1:2:1, black:gray:brown. In a sample of second generation rabbits, there are 10 black, 27 gray, and 16 brown rabbits. Assuming random sample and independent observations, does this sample of rabbits suggest that the actual fur color distribution differs from the genetic model? Include all steps for full credit.

Genetic theory predicts that, in the second generation of a cross of sweet pea plants, blossoms will be either red or white, with each plant independently having a 70% chance of producing red blossoms. Out of 20 plants selected at random from the second generation of this cross, let X be the number that have red blossoms. (a) What is the probability distribution of X?
