If the genotype frequency of a homozygous recessive genotype is equal to 0.023 and a selection coefficient roughly 10% worse than the other genotypes (i.e., s = 0.1), what would we expect its frequency to be after natural selection?
A.) 0.015
B.) 0.0207
C.) It is impossible to answer given the information provided.
D.) 0.0023
c) it is impossible to answer given the information provided.
data is inadequate. in order to find out the answer, absolute fitness value needs to be provided.

Please help with the question: Is the frequency of a
homozygous dominant genotype equal to the proportion of individuals
that show the dominant trait.
3) Is the frequency of a homozygous dominant genotype equal to the proportion of individuals that show the dominant trait? Explain your answer. population is q=0.8 1> In a given population of grizzly bears, 29 of a total of 145 animals exhibit a light fur colour which is controlled by a recessive allele. Four generations later,...
In gerbils there is a recessive mutant gene that causes a lethal condition. For the purpose of this problem let the symbol A denote the normal allele and a the mutant. In heterozygote individuals who carry both versions of the allele (Aa), this causes a white spotting color pattern. Homozygotes for the mutant (aa) die as embryos and are never seen in live gerbils. Since the mutant allele is lethal in the homozygous form, natural selection will occur against the...
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...
In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...
i need some help with this lab ASAP please!
HUMAN GENETICS It to study because of the relatively long life span and the limited number In addition, the number of chromosome pairs (23) increases the possible number of genetic combinations. It is possible, however, to take a sample from human frequency of a trait and the possible ways a given trait is inherited. populations to estimate the Objectives .Investigate the inheritance of some human traits. Estimate the frequency of selected...
Hello, please please please answer these questions! I would
appreciate it!!!
Thank you soooo much!!!!
Questions 2 to 4 are based on the following scenario Question 2: Although the following scenario is hypothetical, it is based on actual facts. Pukaha National Wildlife Centre is a captive breeding facility located in a protected forest area in the lower part of the North Island of Aotearoa, New Zealand. It aims to restore native wildlife, with its initial target on birds. One of...
In recent years, some leopard populations have suffered from a loss of habitat. You are part of a research team that is studying the effects that decreased range has on these populations. Your team observed that a portion of one population relocated to the desert and merged with another small leopard population after its own habitat was threatened by deforestation. You have been assigned to lead the study of this new population and look at its gene pool make-up. In...
Find the calculations for the data of this
population?
a) Calculate the relative fitness for each of the
three genotypes?
b) What is the mean fitness of this population, and
how do you expect it to change in response to selection?
c) Based on the calculations in a), calculate the
values of h and s. What type of selection has occured?
d) If the surviving individuals mate at random, what
will be the genotype frequencies in the next generation (...
You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
I posted this question before but no answer I need to submit in
4 hours, please help.
Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...
