Chapter 4, Problem 7PDQ

As in the plants of Problem 6, color may be red, white, or pink; and flower shape may be personate or peloric. Determine the P1 and F1 genotypes for the following crosses:

(a)

Chapter 4, Problem 7PDQ, As in the plants of Problem 6, color may be red, white, or pink; and flower shape may be personate , example  1

(b)

Chapter 4, Problem 7PDQ, As in the plants of Problem 6, color may be red, white, or pink; and flower shape may be personate , example  2

(c)

Chapter 4, Problem 7PDQ, As in the plants of Problem 6, color may be red, white, or pink; and flower shape may be personate , example  3

(d)

Chapter 4, Problem 7PDQ, As in the plants of Problem 6, color may be red, white, or pink; and flower shape may be personate , example  4

(e) What phenotypic ratios woud result from crossing the F1 of (a) to the F1 of (b)?

Blurred answer
Students have asked these similar questions
The expected ratio of phenotypes among the progeny of a test cross is 1:1:1:1. Out of 200 total resulting progeny, 48 occur in one of the four phenotypic classes. Given this information, which of the following must also be true? a)At least one additional cell must also contain a count of 48. b)The progeny of this cross do not conform to a 1:1:1:1ratio. c)The value of observed - expected for this cell = -2. d)Since 48 is so close to the expected value, there is no need to calculate chi square before drawing a conclusion about the ratio.
Assume performing only one cross, which produced 274 flies, which consisted of 193 wild-type flies and 81 white-eyed flies. (a) Based upon this information, what is the most likely genotype of the female parent? (b) How to confirm the above answer with only the result from this one cross?
Two corn plants are studied. One is resistant (R) and the other is susceptible (S) to a certainpathogenic fungus. The following crosses are made, with the results shown: (see attached) a) What can you conclude about the location of the genetic determinants of R and S? b) What other criteria can be used to determine if a certain trait follows the pattern shown in(a)?
