The higher the proportion of loci that are "fixed" in a population, the lower are that population's
Zanzabum

The correct option is (D) Nucleotide variability and average heterozygosity

The higher the proportion of loci that are "fixed" in a population, the lower are that population's nucleotide variability and average heterozygosity.

<h3>What does it indicate when a gene in a population is fixed?</h3>
  • In population genetics, fixation is the transformation of a gene pool from one in which at least two alleles of a certain gene exist in a given population to one in which only one allele persists.
  • Any allele must eventually be lost entirely from the population or fixed (permanently established at 100% frequency in the population) in the absence of mutation or the heterozygote advantage.
  • Selection coefficients and random variations in allelic proportions determine whether a gene will ultimately be lost or fixed. Fixation may relate to a specific nucleotide location in the DNA chain or a gene in general (locus).

Luden [163]
<h2>Answer is option " 2 & 4"</h2>

Explanation:

  • Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:  
  • m+g/mg : Parental  
  • mg+/mg : Parental  
  • m+g+/mg : Recombinant  
  • mg/mg : Recombinant  
  • m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
  • Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
