a. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay?
b. A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions.
c. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross.
I. Male Drosophila from a true-breeding wild-typestock were irradiated with X-rays and then mated withfemales from a true-breeding stock carrying the following recessive mutations on the X chromosome:yellow body (y), crossveinless wings (cv), cut wings(ct), singed bristles (sn), and miniature wings (m).These markers are known to map in the order:y - cv - ct - sn - mMost of the female progeny of this cross were phenotypically wild type, but one female exhibited ct and snphenotypes. When this exceptional ct sn female wasmated with a male from the true-breeding wild-typestock, twice as many females as males appearedamong the progeny.a. What is the nature of the X-ray-induced mutationpresent in the exceptional female?b. Draw the X chromosomes present in the exceptional ct sn female as they would appear duringpairing in meiosis.c. What phenotypic classes would you expect to seeamong the progeny produced by mating the exceptional ct sn female with a normal male from a truebreeding wild-type…

- this is what i have said about this image so far, what else can be said aswell including the raw count column. " Interpreting the results of an RNA-Seq analysis is pivotal in understanding the underlying genetic mechanisms of diseases such as breast cancer. In this analysis, Figure 1 provides comprehensive data on differentially expressed genes associated with breast cancer. By delving into the provided information, we can gain valuable insights into the molecular landscape of this disease. First focus is on the gene with the highest fold change, EYA4, situated on chromosome 6. With a staggering fold change of 3604.4176, EYA4 exhibits an unprecedented level of overexpression in cancerous cells compared to normal cells. This profound alteration suggests a pivotal role for EYA4 in breast cancer pathogenesis. The log2 fold change of 11.81555 further emphasizes the magnitude of this difference in gene expression. Statistical significance is evident, with an exceptionally low p-value of…arrow_forwardA normal appearing female infant was identified with a positive newborn screen, linked to chromosome 12. Few years ago, her older sibling had developed profound hypoglycemia, liver failure leading to coma, and subsequent irreparable brain damage, following a viral illness. The sibling was subsequently shown by clinical testing to have the same disorder that this female infant is screened positive for. a. What is the most likely diagnosis? b. What biomarkers would confirm this on the newborn screening process? Describe the mechanism that causes this metabolic defect.arrow_forwardA. Clearly there is significant genetic variation associated with susceptibility to COVID-19. Does that mean that the heritability of COVID-19 susceptibility is close to 1? Based on your knowledge, what is the potential role of the environment in determining susceptibility to COVID-19? B. What is the utility of understanding the genetic basis of susceptibility to COVID-19 for medicine and public health? Can you think of potential applications of this knowledge?arrow_forward

What phenotypic ratioswould you expect from crossing strains heterozygous for wild-type and recessive amorphicalleles for each of the genes encoding thesetranscription factors?b. Now assume that either transcription factor issufficient to get blue color. What phenotypicratios would you expect from crossing the sametwo heterozygous strains?arrow_forward11). This pedigree illustrates a family in which some members have a completely penetrant disease caused by a dominant mutation. This mutation is linked at a distance of 10 map units from a SNP marker with three different alleles (1, 2 and 3). The SNP alleles found in each family member are indicated below each pedigree symbol. It is not yet evident whether the very young individuals labeled A and B will develop the disease. a. What is the probability that individual A will develop the disease? b. What is the probability that individual B will develop the disease? 1,3 2,2 1,2 3,2 O 1,2 3,2 A Barrow_forwardIn references to the "alpha-globin gene locus" or "beta-globin gene locus", the term "locus" means A a chromosome region with a cluster of related globin protein genes.

- The drug ivacaftor has recently been developed totreat cystic fibrosis in children with the rare G551Dmutant allele of CFTR.a. Do you think that ivacaftor would be effective onlyin patients homozygous for the G551D mutation,or might it work as well in compound heterozygotes in which one copy of chromosome 7 hadG551D and the other copy a different allele ofCFTR, such as the more prevalent allele ΔF508?(The protein encoded by G551D folds up properlyand inserts into the cell membrane, but is inefficient in chloride ion transport. Ivacaftor increasesthe efficiency of G551D’s ion transport. TheΔF508 protein does not fold up properly and therefore does not get inserted into the cell membrane.)b. Why do you think ivacaftor would be more effectivein children than in older cystic fibrosis patients?c. The scientists who developed ivacaftor had a modelfor cystic fibrosis: a line of cells that grow in culture and that are homozygous for G551D. Thesecells accumulate mucus at their surfaces that…arrow_forwardConsider two maize plants:a. Genotype C/cm ; Ac/Ac+, where cm is an unstableallele caused by a Ds insertionb.

Assume that Ac and care unlinked, that the chromosome-breakage frequencyis negligible, and that mutant c /C is Ac+.arrow_forward1. The pedigree below shows the incidence of rare, autosomal dominant disorder called Ehlers-Danlos disease. The pedigree covers three generations of a particular family and also shows individual genotypes at a potential marker locus (M). a) Indicate the phase of all gen II and III individuals.

Lifestyle choices and environmental exposures can also shape up a disease, how? (Discuss from the aspects of molecular biology) c.

What color intensities will you expect in the spots of oncogenes and tumor suppressor genes?arrow_forwardComplementation tests of distinct recessive mutants, 1 through 8, produce the data in the matrix below. A plus (+) indicates complementation, meaning the phenotype of the combined alleles is wild type, and a minus (-) indicates a failure to complement meaning that a mutant phenotype results.

They undergo a mutation rate that is at least ten times greater than that of nuclear genes There are thousands of copies of each in every cell and their information is redundant They both contain a relatively small number of genes and all are under strong selective constraint They are both involved in cytoplasmic inheritance and approximately 10% of individuals have been found to be chimeras They are paternally and maternally inherited, respectfully, and there is therefor no opportunity for recombination to occurarrow_forward
