On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. In fact, if you are a pencil bear and a great surfer, you must have silky fur. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky Fur Wild-type Fur SS 40 10 Ss 100 0 ss 10 150 The S allele frequency in this population is 0.20, and the genotypes are in Hardy-Weinberg proportions at the locus. In a mating of Ss (heterozygous) pencil bears, what is the expected proportion of offspring that will be excellent surfers?

    please explain the answer On the island of Bilago, on the Planet Ceti Alpha 6, there lives a population of armadiles (cross between an armadillo and a crocodile). A portion of these armadiles have small teethc as a result, they are vegetarian. Tooth size is determined by a single autosomal locus with two alleles: T (trait allele) and t (wild type allele). In a recent study. researchers collected the values in the following table: Table 1. Counts of armadile tooth...

    Please show work. Thank you. 12. A small portion of deer have a trait called leucism, which is white coat. The frequency of the leucitic phenotype is 0.00005 (or 1/20,000). Leucism is recessive to wild type color. Assuming that the deer population is in Hardy-Weinberg equilibrium fr A. Estimate the frequencies of the recessive leucistic allele (I) and the dominant wild type allele (L) B. Estimate the frequency of deer with heterozygous genotype C. For the calculations above, you assume...

    Type 2: In a population of 2000 gaboon vipers, a genetic difference with respect to venom exists at a single locus. The alleles are incompletely dominant. The population shows 100 individuals homozygous for the ‘t’ allele (genotype “tt” = poisonous) 800 heterozygous (genotype Tt = mildly poisonous, and 1100 homozygous for eth T allele (genotype TT = lethally poisonous). (a) What is the frequency of the ‘t’ allele in the population? (b) Are the genotypes in Hardy-Weinberg equlibrium?

    A is the normal allele at the Beta-globin locus, but in a malarial region of western Africa, the S allele of this locus is present at a frequency of 0.2. SS individuals have sickel-cell anemia and have only a 10% chance of surviving to reproductive age relative to heterozygous individuals with the AS genotype. Normal individuals with the AA genotype at this locus have an 85% chance of surviving to reproductive age, relative to AS individuals. Assume that at this...

    1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

    The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

    5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...
