The correct option is (B) Fixed.
It is because fixed alleles are the only variants that exist for a gene in a given population. Also, the fixed alleles remain homozygous for all the members present in a population.

When an allele is the only variant in the population it is said to be... Drifted...
A mutated allele is a variant of the original “wild type” allele. A mutated allele can mutate again. The first mutation discovered receives the primary code for that locus, for example, 1xxxxx. How do we code for other mutations at the same gene locus when they are found? Please give an example.
While the HbS allele is the most common variant in West Africa, there are other alleles that confer resistance to malaria. For example, in malaria endemic regions of Southeast Asia, there is another allele, referred to as HbE, which confers malaria resistance to heterozygotes, but has milder health consequences in homozygotes. This variant is fairly common in the population, with allele frequencies up to 25% in some groups, and ____________, suggesting that it has been subjected to positive selective pressure....
why A1 allele become not fixed in the population when the A2 allele is still present in this population?
p is the frequency of a new mutation: -i.e. In a population containing only allele A2, an allele mutates into allele A1 Question: A single mutant allele A2 would start at p=0.1 in a population with ____ (how many) individuals? A.) 10 B.) 5 C.) 20
An allele, A1, in a diploid population of size N, starts at an allele frequency of 0.7. What is the expected allele frequency in the next generation? In the 100thgeneration? What is the probability that the allele frequency will increase in the next generation? If you follow 100 populations that start with the same conditions for millions of generations, how many would you expect to be fixed for A1?

A dominant allele (A) is found at equal frequency with a recessive allele (a) in a population of mice. There is no selective force for this gene (fitness of all genotypes is the same). Which allele is most likely to become fixed in the population over time? A The dominant allele, A B It is impossible for either allele to become fixed in the population C They are both equally likely to become fixed in the population, it is purely...
A population of cats can be either black or white; the black allele (B) has complete dominance over the white allele (b). Given a population of 2,000 cats, 1540 black and 460 white, Determine the allele frequencies of the two characteristics. A population of cats can be either black or white; the black allele (B) has complete dominance over the white allele (b). Given a population of 2,000 cats, 1540 black and 460 white, determine the frequency of individuals with...
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 100 lizards, the “A” allele encodes for spots and is dominant over the “a” allele which encodes for strips. If non-random-mating occurred in this population, meaning lizards only mated with other lizards with the same genotype, how would the allele and genotype frequencies change after two generations of non-random mating? A = 0.5 a = 0.5 I would really appreciate if you could provide an explanation for the steps. Thank you!
