In the following breeding scheme, what is the probability of obtaining genotype RrYyTtss in the F2?

P RRYYTTSS x rryyttss

F1 RrYyTtSs x RrYyTtSs

F2

Expert Solution

Ans-

Rr × Rr Yy × Yy Tt ×Tt Ss × Ss

1RR:2Rr: 1rr 1YY:2Yy:1yy 1TT:2Tt:1tt 1SS:2Ss:1ss

2/4 Rr 2/4 Yy 2/4 Tt 1/4ss

Probability of obtaining individual with Rr and Yy and Tt and ss

2/4 × 2/4× 2/4 × ¼= 8/256= 1/32

Therefore, the probability of obtaining genotype RrYyTtss in the F2 is 1/32

The authors genotypes 287 F2 plants. What are the expected numbers of genotype, given the proportions you determined in b? (1 pt) 72 homozygous Dn, 72 homozygous Dg, 143 heterozygous DnDg <- this is the answer I found Imagine that the observed numbers of F2 individuals of each genotype are: 3 DnDn, 144 DnDm, and 140 DmDm. Perform a Chi-square analysis to determine whether the authors can reject the null hypothesis of equal segregation of alleles.

What is the probability of obtaining a sample mean greater than M=70 for a random sample of n= 16 scores selected from a normal population with a mean of μ=60 and a standard deviation of σ=20?

In this activity, you will determine the probability of obtaining one of these disproportionate ratios if...

In this activity, you will determine the probability of obtaining one of these disproportionate ratios if we assume that nature alone is responsible for these obscure results. In order to determine these probabilities, you will use the Normal approximation to the binomial. 1. Outline the binomial model for the number of boy births in the next 1000 births assuming that births are produced according to the natural ratio of 51.2% chance of a boy. 2. Outline the Normal approximation to...

Suppose that the probability of obtaining a particular grade in an undergraduate statistics course, is defined by the following table: grade A B C D F probability .25 .35 .2 .15 .05 (a) Using the usual numerical values for the grades, define the corresponding random variable, X, and its probability mass function, p(x). (b) Calculate P(X ≤ 2), P(X < 2), and P(X ≥ 3). (c) Plot the cumulative distribution function F(x). (d) Compute the mean µ = E(X).

Good performance (obtaining a grade of A+) in this probability class depends on your attendance (A) and completion of assignments (C). The probability that you will receive a grade of A+ are 95%, 75%, 50%, and 0%, if you attend the class and complete the assignments, if you attend but do not complete assignments, if you do not attend but complete assignments, and if you neither attend nor complete assignments, respectively. Further assume that if you attend the class, there...
