In studying the gene pool of a population, you find that 21% of the population exhibits the recessive trait for eye color and th
e other 79% of the population exhibits the dominant trait. The dominant allele has complete dominance over the recessive allele. How would you use this information to solve for the frequency of the recessive allele?
In order to solve this problem we use these formula: <span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population q = % recessive allele in the population p2 = % homozygous dominant individuals q2 = % homozygous recessive individuals 2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>
A glucose molecule enters glycolysis in the cytoplasm of the cell. The glycolytic reactions break down one molecule of glucose into two molecules of pyruvate. Each of the pyruvate molecules is then decarboxylated and is oxidized into acetyl CoA. Acetyl CoA enters Kreb's cycle. Acetyl CoA is completely broken down into CO2 and H2O in Kreb's cycle. In this way, glycolysis and Kreb's cycle break down the glucose molecule into CO2 and H2O in a stepwise manner.
