Summary Introduction

To determine:

The effect of late acting dominant lethal alleles on the frequency of the population.

Introduction:

The trend of marrying late and having children later in life is observed in developed countries. This practice has many positive as well as many negative effects. Out of many negative effects one of them is the increased risk of attaining genetic disorders in the off springs.

2) The year is 2050. The climate has continued to warm. Areas in northern Canada and Alaska are without snow or ice; the average annual temperature has risen and previously snow-covered areas are now shrub land and some temperate forests. What effect would such a climatic change have on the gene pool of the rabbits? All BUT ONE could apply.   A) The allelic frequency has most likely shifted to 85% GG and 15% gg.     B) The dominant allele in the gene pool would become G, the previously rare allele.     C) The allele for white, g, would be scarce and perhaps nonexistent in the population.     D) White rabbits would be at a disadvantage in terms of camouflage and would likely fall prey to predators.
Give typed full explanation
This lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!
