Explain how the founder effect can lead to a descendent population that differs greatly from its parent population over a relatively short period of time.

Describe the features of the fluid mosaic model of the cell membrane in detail

Evolution determines the change in inherited traits over time to ensure survival. There are three variants identified as Variant 1 with high reproductive rate, eats fruits and seeds; Variant 2, thick fur, produces toxins; and Variant 3 with thick fur, fast and resistant to disease. These variants are found in a cool, wet, and soil environment. In time 0 years with cool and wet environment, the population is 50,000 with 10,000 Variant 1, 15,000 Variant 2, and 25,000 of Variant 3. Two thousand years past, the environment remained the same with constant average temperature and rainfall. Variant 1 with a population of 26,000, Variant 2, 35,000, and Variant 3, 62,000. A disease spread throughout the population. However the population increased to 72,000. Determine the percentage increase in the population of the variants.

In a species of beetle, the size and color of the wings are controlled by two distinct genes. There are two alleles for the size gene: the big allele makes wings large, and the small allele makes them smaller. There are two alleles for the color gene: red and yellow. You are able to estimate the frequency of the four haplotypes from a museum collection from 60 years ago. You also estimate haplotype frequencies in the present day. The data are shown in the table below. Museum (60 ya) Present day big/red 0.69 0.5452 big/yellow 0.00 0.1448 small/red 0.09 0.2348 small/yellow 0.22 0.0752 A) What is linkage disequilibrium (LD) between the size and color loci in the museum collection? What is LD in the present day? B) Assuming one generation per year, what is the recombination fraction between the size and color loci?
