Manx cats possess a heterozygous mutation resulting in a shortened or missing tail. If they

receive 2 of these recessive alleles, it acts as a recessive lethal. Let’s say that this allele has a

frequency of 0.15 in a population due to genetic drift in a small population. Based on natural

selection, would you expect the allele frequency to change in the next 3 generations?

Thoroughly explain your results.

Answer #1

The chance of allele frequency to change in the next 3-generations is totally dependent upon the number of offsprings in all the three generations as we are provided with the data of frequency of 0.15 in a population. So without knowing the number of offsprings in all three generations, we cannot say that there would be change in allele frequency.

    In cats, a condition known as Manx is a dominant disorder resulting in abnormal tail development. Manx cats are heterozygous for the Manx gene, whereas cats with normal tail lengths possess two recessive alleles. The homozygous dominant condition is lethal. Is it possible to have a pure breeding Manx cat? Cross two Manx cats and prove your answer.

    In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...

  • A plant called blue-eyed grass normally produces blue flowers. However, plants producing white flowers also occur,...

    A plant called blue-eyed grass normally produces blue flowers. However, plants producing white flowers also occur, because an allele for the gene coding for the protein that produces the blue pigment is non-functional. This white-flowered allele (W) is dominant to the blue-flowered allele (w), but generally occurs at very low frequency in populations. Suppose you crossed a homozygous dominant plant with a homozygous recessive plant, and the result is 16 seeds. If you plant these, assuming simple Mendelian genetics, how...

    The Kermode Spirit bear is an alternate phenotype of the species Ursus americanus (black bear) in British Columbia that has striking white fur. It was determined in 2001 that a single nucleotide change from G to A results in the replacement of Tyrosine with Cysteine at codon 289 in the melanocortin 1 receptor gene (mc1r; Ritland et al. 2001 Current Biology). This allele (W2) is recessive to the wildtype allele (W1), and occurs as a novel mutation in 1 out...

    QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...
