Male sterility in maize is determined by which type of mutation (in this case)?
Hi, I was uncertain about what would be the correct alternative on a question I have to answer, regarding male sterility in maize. Below, I’ll insert the problem and what I have thought so far (also, my apologies if the sentence is not well formulated, I’m translating it from my native language).

Was Lewis just mapping them on a linkage map based on mutations?
Hi guys,
So I've spent a few days reviewing the genetic tools used in labs, but can't quite find the distinction between a few of the methods.
1. RT-PCR is used to determine if a specific gene is expressed; however, RNA-seq appears to do the same thing. I understand that RT-PCR uses a specific primer and thus tests the expression of one gene. Does RNA
So I'm trying to figure the number of phenotypic classes that can occur in an F1xF1 cross of 2 different parents one the female being homozygous w,m,f and the male being WT. This is occurring on the 1st chromosome of the D. melanogaster so it is sex-linked.
So I know there are 3 different alleles we are looking at so to get the classes in a non-sex linked chromosome

I got my finals in a few days and was wondering if anybody could give me the link to the answers to the review questions in this book? I finished all the questions but I'm not entirely sure how to check them as there is no answer section and the wwnorton.com/studyspace doesn't have anything either. Thanks
Ok no matter how many times i am explained this it makes no sense and its not in the book i use so i have nowhere to turn, can anyone help me understand whats happening with these plates it looks like a bunch of dots to me i don't see how its getting those genotypes from the given information.

The first two pregnancies for a couple result in late term stillbirths. The reproductive histories of both families, over 3 generations, were compiled. A pattern of frequent miscarriages, stillbirths and malformed babies that died shortly after birth were seen in the husband's family. The husband has a karyotype done, which shows that he has the normal number of chromosomes. Wh

You have 4 primers that can be used for PCR amplification of a 3000 bp plasmid. The locations of the 5’-end of each 20-nucleotide primer is shown in the diagram below. What will be the size of the PCR product when the following pairs of primers are used together in the PCR reaction (if no product will form, write-in 0 bp)
4. The diagram below outlines a molecular test to determine if individuals have the sickle-cell allele. First the region is amplified by PCR and then digested with a restriction enzyme. The two primers are located just to the left of the “1” site and just to the right of the “3” site. a. If the distance between site 1 and 2 is 250bp and the distance between site 2 and 3 is 500b
Fly larva mutations for Gap, pair-rule, and maternal effect genes
The title say most of it. I'm supposed to draw the mutations in the Drosophila larva, but I also need to label the structures which my textbook is not helping me much with. So far I just know that the mutants are stubby little creatures... I also need to list the specific gene mutated since I guess these are gene families???
Use the following hypothetical information to answer the next two questions. Eye colour in humans appears to be controlled by multiple alleles. The green allele and the brown allele are dominant to blue. Green eye colour is expressed only in the absence of a brown allele. Red-green colour blindness is a sex-linked trait. Red-green colour blind

How do the eight palindromes in the male specific region of the Y chromosome (MSY) prevent the chromosome degeneration that one would predict on the basis of Muller’s ratchet? What role has inversions played in the development of the MSY?
Indicate which allelic combinations each individual has
I know the answer already because the key was given but I don't know why the answer is what it is. I thought the progeny in generation III all had parental allelic combinations but that's not so. Why is that?
People with the recessive disease, Purple Tongue Syndrome, are unable to make the enzyme Blue Pigment Decolorase (BPD). You isolate mRNA from a person (P) afflicted with the disease and from a normal person (N) and do the following: i. Mix excess P mRNA with cloned genomic DNA carrying the BPD gene and, separately, mix Normal (N) mRNA with the same DNA. ii. Raise the tempe

Creation of CFTR Knockout Embryonic Stem Cells by Positive-Negative Selection
I am having trouble understanding what is going on here. What I got thus far is that the more preferred fate is Homologous recombination (targeted approach). Next, you basically plate the ES cells that are both neomycin & ganciclovir resistant (homologous recombination). I basically do not know if I am on the right track. Any feedback of any sort will help.
I was wondering whether the distance between loci ever change?
For example if eye color was on gene A and pupil size on gene B, the distance between gene A and gene B is 50 cM. Is there a scenario where A and B is not 50?
My teacher said it can, but I don't understand. Isn't the distance between certain genes always fixed?

In human gestational develop, abnormalities of the closure of the lower part of the midface can result in cleft lip, if the lip alone is affected by the closure defect, or in cleft lip and palate (the roof of the mouth), if the closure defect is more extensive. Cleft lip and cleft lip with cleft palate are multifactorial disorders that are threshold traits. A family with a his
