Chapter 12, Problem 3S
Summary Introduction
To explain:
The outcome of the cross of yellow mice and to test the hypothesis.
Introduction:
Lethal genes or alleles are the genes that can cause death of an organism if present in the homozygous condition (i.e., both alleles of the individual are identical lethal alleles). In the given case, when yellow mice were crossed, there were two yellow mice and only one black mouse.

You perform a cross between a parent with the genotype WWiiNNttEErr and another parent that is
wwllnnTTeerr. All genes are unlinked except for W and I which are 22 mu apart.
You take an F1 from this cross and cross it with an individual that is wwiiNntteerr.
a) What is the probability that this final cross yields an offspring that is wwiinntteerr?
b) What is the probability that this final cross yields an offspring that is NNTT or Nntt. (You can
ignore all of the other genes for this question.)

- Pure-breeding parental strains of corn with the purple, smooth and yellow, wrinkled phenotypes were crossed to produce an F1 generation, which were then crossed to produce the F2 generation. Complete the diagram showing the results of the cross below. (I included an enlarged picture of the corn as well)arrow_forwardA Neurospora colony at the edge of a plate seemed to be sparse (low density) in comparison with the other colonies on the plate. This colony was thought to be a possible mutant, and so it was removed and crossed with a wild type of the opposite mating type. From this cross, 100 ascospore progeny were obtained. None of the colonies from these ascospores was sparse, all appearing to be normal. What is the simplest explanation of this result? How would you test your explanation? (Note: Neurospora is haploid.)arrow_forwardYou have a garden and some pea plants have dark leaves and others have striped leaves. You conduct a series of crosses (1 through 5) and obtain the results given in the table. What is the genotype of the parents in cross 1? A) Aa x aaB) Aa x AaC) aa x aaD) AA x aaarrow_forward
- When crossing a true breeding white mouse with a true breeding brown mouse your friend tells you she recovered all black mice. But then when she crosses the F1 mice to each other she recovered 28 black mice, 8 brown mice, and 13 white mice. Can you help her explain these results? (Type out the cross and include genotypes of as many mice as possible. What phrase best describes this phenomenon? How many genes are involved are they linked or unlinked? Etc.)arrow_forwardA series of crosses were performed between pure breeding lines of mice with different coat colours. a) Based on the results of the crosses, describe the type of gene interaction that gives the white phenotype. Explain your reasoning. b) Determine the order of the function.arrow_forwardNicotiana glutinosa (2 n = 24) and N. tabacum (2 n = 48) are two closely related plants that can be intercrossed, but the F1 hybrid plants that result are usually sterile. In 1925, Roy Clausen and Thomas Goodspeed crossed N. glutinosa and N. tabacum and obtained one fertile F1 plant . They were able to self-pollinate the flowers of this plant to produce an F2 generation. Surprisingly, the F2 plants were fully fertile and produced viable seeds. When Clausen and Goodspeed examined the chromosomes of the F2 plants, they observed 36 pairs of chromosomes in metaphase I and 36 individual chromosomes in metaphase II. Explain the origin of the F2 plants obtained by Clausen and Goodspeed and the numbers of chromosomes observed.arrow_forward
- The genotypes of F1 individuals in a trihybrid cross are LlMMNn x llMmNn. What is the probability that the F2 offspring will have an LlMmnn genotype? Use the forked-line method in solving the problem.arrow_forwardWhy are some crosses not performed in a complementation matrix?arrow_forwardThe table below shows the progeny of a test cross of a heterozygote (HhFfGg). Each row shows the number of progeny that inherited each combination of alleles from the heterozygous parent. You've already determined the gene order (G is in the middle) and labeled each type of progeny. Using this information, what is the recombination frequency between H and G? Alleles: Type: HGF hgf HgF h Gf Hgf h GF HGf hg F O 0.543 0.302 O 0.241 O 0.23 0.139 Parental Parental DCO DCO SCO (H-G) SCO (H-G) SCO (G-F) SCO (G-F) Count: 124 119 15 18 51 55 38 40 O The correct answer is not available.arrow_forward
- In letter B: If the map distance equals the number of recombinant/total of offspring, wouldn't it be 24/806 x 100? Wouldn't we add both recombinants? Can you explain letter C? I don't grasp that concept well. And since I'm using my question already, would you be able to answer D. Thank you!arrow_forwardA cross in plants is done between the parents CCDD and ccdd to create a dihybrid F1 plant. This F1 plant was subsequently test crossed to a ccdd plant and you find the the progeny as follows: 40% CD 40% cd 10% Cd 10% cD If you did a similar experiment in which the parents were changed to ccDD and CCdd, what percentage of the test cross progeny would have the cd phenotype? 40% 80% 10% 20%arrow_forwardAn ebony strain of flies was discovered to be sensitive to carbon dioxide. Crossing a female sensitive strain with male resistant strain gave all sensitive offspring. The offspring of an F1 female crossed with a resistant male were all sensitive. Using the following key to your illustrations using shapes, make a reciprocal cross up to the F2 generation. Put your illustrations in the space provided below. Label the phenotypes of all individuals in the reciprocal cross. Adjust spacing, if necessary. Make sure that the complete cross(es) can fit the same page.
