Allele

for endurance and speed. Africans have the lowest incidence of the ACTN3 mutation while Asians have the highest. This could be because of how much energy was needed for these individuals in different parts of the world. It was interesting to see the allele frequency for this gene in elite athletes and how it was expressed based on the sport or level of complexity that the athletes performed at. It was striking to see that the genotype frequency displayed from this study showed that power…

plants and outlined three laws oh inheritance. First, the Law of Dominance is expressed where one allele dominates over recessive one. For instance, during the experiment with the pea plants, the parents were both homozygous (with identical forms of alleles YY and gg. In the F1-generation the plants were heterozygous (Yg), however with all seven pea plant traits, he examined that yellow (Y) allele appeared to be dominant over the green (G). If the genotype is Yg (heterozygous), the phenotype…

mammalian receptors are the receptors to which extracellular bitter substances bind to which trigger the activation of the G-proteins and is responsible for PTC perception. However, the inability to taste PTC is due to the inheritance of two recessive alleles, one from each parent. Some studies have also shown that there are other genes or environmental factors that influence PTC tasting. Research has shown that due to Mendelian inheritance, 30% of the human population are non-tasters while…

chromatids. In anaphase II, a new law is introduced which is the Law of Segregation. The Law of Segregation states that each allele that is responsible for a certain trait is separated into their individual cells. For example, big A has an allele that is responsible for being tall, small a has an allele for being short, small b has an allele for blue eyes, and big B has an allele for brown eyes; these different chromosomes will be separated into different gametes. This process creates a genetic…

recessive allele from both parents. 4. The significance of the fact that couples who cannot taste PTC never has children who can taste the PTC is because it is genetic. So children that came from parents that are not taster to PTC, they will be born without the gene because their parents never had the gene. 5. Based on this data, I can conclude that PTC blindness has two characteristics: one depend on the dominant allele being a taster and the other one depend on recessive homozygous allele…

place in very small inhabitants, where rarely occurring alleles face a better opportunity of being absent. Once it starts, genetic drift will carry on up until the allele involved is missing by the inhabitants or up until it is the lone allele existing in a population at a specific locus. Genetic drift is normal following population bottlenecks, which severely cut the amount of a population. Now, the result is the loss of extraordinary alleles and a decline in the gene pool. Genetic drift can…

from self-reported questionnaires. The lack of heterogeneity for the 20 confirmed loci means that the self-reported data did not skew the results. The additive genetic effect (estimate of the quantitative change in a trait that is substituting one allele with another in an interbreeding population) model statistics of 402,951 SNPs was compared and showed an increase deviation of the observed statistics from the null distribution (Weedon, et al., 2008). It was observed that 27 independent…

Cystic Fibrosis Cystic fibrosis is a recessive genetic disease in which the lungs and digestive system get filled and clogged up with think sticky mucus. Cystic Fibrosis can also be called Cystic fibrosis of the pancreas, Fibrocystic disease of the pancreas, Mucoviscidosis, Mucoviscidosis of the pancreas, Pancreas fibrocystic disease, Pancreatic cystic fibrosis. This disease affects the cells that control digestive fluids, sweat and mucus in the body, and makes these fluids thicker and…

B. 2. (3.) The percentage of Allison’s egg cells that she produces during her lifetime that will carry the recessive allele and the X chromosome is seventy five percent. For the fact, twenty five percent of the cell will carry homozygous recessive allele and X chromosome, the other fifty percentage will carry heterozygous recessive allele and X chromosome. (4.) A. Twenty Five Percent B. No. C. (X)R (X)r (X)R (X)R(X)R - Female homozygous dominant (X)R(X)r - Female…

Week 3 Assignment Please thoroughly answer the following 5 questions. 1. By conducting testcrosses, researchers have found that the sweet pea has seven linkage groups. How many chromosomes would you expect to find in leaf cells? The cell leaf would be able to contain 14 chromosomes within the sweat pea. The sweat pea should have seven chromosomes per set. The sweet pea should contain two sets of chromosomes. 2. Explain why inversions and reciprocal translocations do not usually cause…
