- Please help answer question 1 What would a pedigree of Greg and Olga’s families look like? Concentrate simply on family relationships and aff ected persons.Interpret the result of your Chi-squared test. How many gene pairs were responsible for eye color in flies as associated with sex? What gene interaction was present in the gene/s for eye color? What is the genotype of the possible P1 & P2 that produced this F2 population? (Remember to indicate your gene notation).Please answer fast 7. What is true about the strategy of selective breeding? Choosing parents with the best phenotypes to pass their alleles to their offspring Choosing parents with the greatest number of alleles to pass them to their offspring Choose parents with best alleles to pass them to their offspring Choosing parents with the best genotypes to pass their alleles to their offspring. 8. What best describes the relationship between genetic distance and frequency of recombination? Genes that are far apart have a 50% crossover rate The closer are the genes, the less crossover there is between them Double crossover makes the estimation of genetic distance difficult Crossover is the best way to estimate the genetic distance 9. You have a population of sheep; You want to start a selection program to maximize production of wool. What is the phenotypic feature that you would consider to pick the parents of the breeding program? Explain. 10. The difference between a…
- Please answer fast Using a Punnett square, perform a trihybrid cross on the following traits in hybrid form: Height - Tt (tall and short)Flower color - Pp (purple and white)Seed shape - Ss (smooth and wrinkle) Give the phenotypic and genotypic ratio.You are studying three traits in a goldfish variety; body colour (A or a), tail length (B or b) and shape (C or c). Note: Use the uppercase letters for the alleles associated with the dominant phenotypes and the lowercase letters for the alleles associated with the recessive phenotypes. Assume that each of these traits is regulated by one gene. Photo credit https://www.petmd.com Part A. You mate a gold fish (P1) with a white fish (P2) and obtain 100 fish in F1, of which 50 are gold and 50 are white. Write two sets of the possible genotypes of the parental and the resulting F1 fish by filling in the table below. Sets P1 P2 F1 gold fish F1 white fish 1 2 Part B. You cross a true breeding gold fish having long curly tail (P3) with a true breeding gold fish having short and straight tail (P4). All of the resulting F1 fish have long straight tails. Write the genotype of the parental fish (P3 and P4) using the outlined nomenclature.…I'm confused about how I would figure out these two questions as I don't really understand the difference or where to start. What would genotypic frequencies be for Wildrose at pt-8 if it were in equilibrium? and How many individuals (to 2 decimal places) of each genotype would there be from Wildrose at pt-8 if it were in equilibrium?
- Please answer fast 1. How would immigration affect allele frequency? Write a protocol for a simulation testing the effects of immigration on a population. Your new phenotype will be garbanzo beans. Write in a low immigration scenario (one individual per generation) and a high immigration scenario (five individuals per generation). 2. Based on the simulations you’ve already done, what is your hypothesis for how the garbanzo bean frequency will change over four generations?Biology Q 1: The following monohybrid cross is made: GG x gg (the parental generation). G (green seeds) is completely dominant to g (orange seeds). Along with this parental cross write out the F1 and the F2 generations. Indicate the genotypic and phenotypic ratios in each generation. (note: don't just give the ratio; for instance instead of writing just 1:1, write1 green: 1 orange or 1:1 green:orange.A population of frogs consists of 1000 individuals of which 400 are red. Red is recessive to Green. What is the frequency of the dominant allele and the recessive allele in this population? What is the frequency of individuals with homozygous dominant phenotypes? Please answer and show all work, thank you!! :)
- ACTIVITY 3: Incomplete dominance vs. codominance Coat color in dragons is controlled by 2 alleles. A black dragon is crossed with a white dragon and all of the offspring are gray. Are the alleles incompletely dominant or codominant? ___ Explain (how do you know)? What would offspring of the other type probably look like? __The genetic identity of the female parent is RrGg and the genetic identity of the male parent is Rrgg. They produce 320 offspring together from a single mating: 57 red-eyed females with grey bodies, 61 red-eyed females with yellow bodies, 22 brown-eyed females with grey bodies, 20 brown-eyed females with yellow bodies.59 red-eyed males with grey bodies, 63 red-eyed males with yellow bodies, 20 brown-eyedmales with grey bodies, 18 brown-eyed males with yellow bodies. Show the simultaneous transmission of the two genes involved to give rise to the progeny given with the use of genetic diagrams and summaries as required. (Hint: you are only requiredto show the simultaneous transmission from the P to F1 generations)TOPIC: GENE INTERACTION AND EPISTASIS Two pure-breeding (homozygous) lines of shrubs were crossed as follows: P1 phenotype red leaves X green leaves P1 genotype ___________ _____________ F1 phenotype 100% green leaves with white flecks F1 genotype ___________ Crossing the F1s produced: F2 phenotypes F2 genotypes 123 green leaves w/ white flecks ____ 44 green leaves ____ 63 red leaves ____
