Flies segregate for a viable (V) and lethal (L) allele. VV individuals survive while LL die at the juvenile stage. Researchers established two populations with V at a frequency of 0.5 and monitored allele frequencies. Draw what you think should happen to the V allele and upload a screen shot or photo. You could also make a quick image in powerpoint and upload that.

A test cross is a mating in which two parents (P generation) are crossed to give F1 (first filial generation) offspring, and then two F1 parents are crossed to give F2 (second filial generation) offspring. By tracking offspring through two generations, a test cross can reveal patterns of inheritance for particular genes. 9. In a cross between a b.ck and a white guinea pig, all members of the F1 generation are black. The F2 generation is made of % black and 4 white guinea pigs. Diagram this cross, and list the genotypes and phenotypes for each generation. !!

Different species of crickets have distinct songs, andthey use these songs for mate recognition. Researcherscrossed two species of Hawaiian crickets (Laupala paranigra and L. kohalensis) whose songs are distinguishedby pulse rate (the number of pulses per second; Shaw etal., Molecular Ecology 16, 2007, 2879–2892.) Then, theymapped QTL in the F2 population derived from thiscross. Six autosomal QTL were detected. The mean traitvalues (pulses per second) at the three genotypic classesin the F2 for each QTL are shown in the table below,where P indicates the L. paranigra allele and K indicatesthe L. kohalensis allele.a. Calculate the additive (A) and dominance (D) effectsand the D/A ratio for each of the six QTL.b. Which of these QTL shows the greatest amount ofdominance?c. Which of these has the largest additive effect?d. The mean pulse rate for L. kohalensis is 3.72, and it is0.71 for L. paranigra.

I need help calculating observed allelic frequencies. I'm in a biology lab and we did a classroom experiment where we were each given genotypes and simulated multiple generations by coinflip. This is the end data after multiple generations and we need to extrapolate p & q: AA individuals - 2 Aa individuals - 13 aa individuals - 5 My understanding is that the genotypic frequencies would simply be their %. So AA would be 0.1, Aa would be 0.65, and aa would be 0.25. This should mean that AA = 0.1 = p^2 and aa = 0.25 = q^2. Which should also mean that taking the square root of these numbers would give me p and q.... but they don't add up to 1. Squaring them gives me a p value of ~0.32 and a q value of 0.5. How is this possible? Shouldn't this method work to give me p and q since I know the exact genotypic frequencies? If anyone can clear up why this doesn't work, I would be extremely appreciative. Thank you!

You counted approximately 360 fruit flies that have vestigial wings, a recessive trait. How many flies are homozygous dominant? O 640 О 320 O 240 О 160 O 400
Tay-Sachs is a recessive lethal disease in which thereis neurological deterioration early in life. This diseaseis rare in the population overall but is found at relatively high frequency in Ashkenazi Jews from EasternEurope. A woman whose maternal uncle had the disease is trying to determine the probability that sheand her husband could have an affected child. Her father does not come from a high-risk population. Herhusband’s sister died of the disease at an early age.a. Draw the pedigree of the individuals described.Include the genotypes where possible.b. Determine the probability that the couple’s firstchild will be affected.
Entomologists at the New York State Department of Agriculture are interested in determiningthe connection between pest insects infesting crop plants with populations of the same insect-infesting native plants in natural habitats. Long-term trapping and monitoring studies have estimated that on average 3% of the populations move between habitats (farm to natural and vis versa) each generation. A new insecticide resistance allele (∆K) has begun to increase in frequency in agricultural populations. A genotyping survey at this locus of 50 individuals in each population has revealed the following genotype counts:4a. Based on the effects of migration alone, what will the frequency of ∆K be in the forestpopulation in the next generation? 4b. If migration was acting in here without selection, what would the frequency of ΔK be in the agricultural population in the next generation? 4c. If the natural forest population was substantially larger than the agricultural population, how might…

population is black in colour but about 1/4 of them are white. gene (B) that produces an enzyme that converts a pigment molecule to produce the Black colour. There are 2 alleles of this gene - the dominant B and the recessive b. DNA analysis shows that black individuals have either a BB or Bb genotype and that white individuals have a bb phenotype. However, you have discovered that a small percentage of White individuals have either a BB or Bb genotype. Explain two reasons that could explain this apparent anomaly. They have a BB or Bb genotype but a white phenotype.
