Fitness here represents reproductive fitness.
For an organism to be fit, it should have maximum reproductive capacity and should have the able to survive in extremes of environment.
Therefore it is better for an organism to produce more offspring over the course of their life time in order to be fit.
This concept of reproductive fitness was given by darwin.
This fitness ensures the ability of an organism to survive and produce more offspring.

1. Of what is FST a measure? What are some problems with this measurement? Fixation index (Fst) is an measure of genetic differences among subpopulations. Measures how genetically similar two populations are to each other. (is this correct) Some problems with this measurement ???? 2. What is sexual selection? What is natural selection?

(12 points) Suppose there are two types of people: high-ability and low-ability. The schooling required to obtain a particular diploma costs a high-ability person $8,000 per year, and it costs a low-ability person $10,001 per year. Firms wish to use this diploma as a signal of an individual’s ability. The firms intend to pay workers such that the present value of lifetime earnings for a worker without the diploma is $250,000, and the present value of lifetime earnings for a...

A. Organisms heterozygous for inversions and translocations are
viable and able to produce progeny but usually in fewer numbers.
Explain why this is so in general terms.
B. Also, explain how would you distinguish among pericentric
inversions, paracentric inverisons, reciprocal translocations and
non reciprocal translocations as sources of semi-sterility. You
need to consider meiotic figures.
C. How can these chromosome aberrations be used to map genes to
chromosomes or linkage groups. You may use a two-point mapping
system as an...

A Haploid yeast strain that is deficient in its ability to make arginine, is crossed to a different haploid yeast strain also unable to produce arginine. The resulting diploid, F1 strain is able to make its own arginine. What is the best explanation? Each deficient haploid strain possessed a mutant allele, but not in the same gene, thus the diploid had 1 functional copy of each gene The defective arginine biosynthetic enzymes, made from the mutant genes, were able to...
