Homework Answers
there are 3 alleles which determines the phenotype.
we can can have True breeding grey, true bredding black, true breeding grey , means the alleles are white, black and grey.
let the alleles be B-black, G-Grey, W- white
BB-black, GG-Grey WW-white
progeny of black and grey are slate so BG- slate
progeny of white and grey are silver so WG- silver
there are only six phenotypes, the next genotype is WB its phenotype is steel.
Steel * Silver
WB * WG
| W | B | |
| W | WW( white) | WB ( steel) |
| G | WG (Silver) | BG ( slate) |
so the proportion is
1/4 white, 1/4 silver, 1/4 slate, 1/4 steel
so the answer is B) 1/4 white, 1/4 silver, 1/4 slate, 1/4 steel

A pure-breeding strain of guinea pig with black fur is crossed to a pure breeding strain with white fur. A number of possible progeny phenotypes are listed below. What would each phenotype indicate about the dominance relationship between alleles of this locus? (i) All the progeny are white [1 mark] (ii) All the progeny are black [1 mark] (iii) All the progeny are grey [1 mark] (iv) All the progeny have patches of white and black fur [1 mark]

3. Consider two traits for a hypothetical animal fur color and ear length. Each trait is controlled by one gene with two alleles. Black fur is dominant to gray fur and long ears are dominant to short. The genes for the two traits are located on different chromosomes. Note: In the following problems, you need to take both traits into account simultaneously a. You cross a true breeding black long-eared male with a true-breeding gray short-eared female. What is the...

two questions: 1) In one experiment, Mendel crossed a purple-flowered, tall plant that had come from a previous hybridization (i.e., it was not true breeding) with a white-flowered, dwarf plant. The results were as follows: • Purple flowers, tall 47 • White flowers, tall 40 • Purple flowers, dwarf 38 • White flowers, dwarf 41 What are the genotypes of both parent plants and all of the 4 classes of progeny? 2) Fur color in tribbles is determined by a...

5. In nasturtiums, flowers may be single (one layer of petals), double (two layers of petals) or superdouble (many layers of petals). Superdouble plants are female-sterile. 1. true-breeding single X true-breeding double → Fı single → F2 78 single : 27 double 2. true-breeding double X superdouble → 112 superdouble : 108 double 3. true-breeding single X superdouble → 8 superdouble : 7 single 4. true-breeding double X superdouble progeny from cross 3 = 18 superdouble : 19 single 5....

You cross two crows, one with yellow legs, and the other with green legs. All of the F1 offspring have purple legs. Leg pigment is produced by the pathway in Fig.3, where the dominant alleles (Y and G) produce functional versions of enzymes Y and G, and the recessive alleles (y and g) produce nonfunctional enzymes. What genotype frequencies do you expect to see in the F2 generation? O all purple 9 green: 3 purple: 3 yellow 9 purple: 3...

Question 2b) You are studying a flowering plant that produces remarkable bright green flowers in its wild type. Your colleagues have discovered two new mutant lines of this plant. One new line breeds true for a yellow flower color. Another new line breeds true for a blue flower color. Your group does the following crosses and makes these observations: yellow X green ⇒ F1 is all green ⇒ F2 75% green and 25% yellow blue X green ⇒ F1 is...

A Gumball machine has a number of different colors available: There are a random number of yellow, blue, white, green, black, purple, silver, cyan and magenta gumballs and one red gumball. With a pocket full of quarters, you have set your heart on getting that single red gumball. So, write a program that will simulate buying gumballs until you get the red one. (Using Python) To start with, the number of gumballs for each color are randomly chosen as follows....
