For the genetic trait of interdigital hair (hair between your knuckles), this phenotype is controlled by one gene. In a population, you determine that the frequency of the alleles is 0.55 H and 0.45 h, with HH being dominant and hairy. If the observed genotype ratio is 0.25 HH, 0.55 […]

Explain the advantages of Nitrogen fixing plants to the humans and its role within the ecosystem in detail.  Browse the Internet and select a way (other than giving the oxygen) that plants are useful to the humans.  Write down a 250 word summary regarding the plant benefit you chose.  a) […]

1. To study the process of DNA replication, you add the nitrogen isotope N-15 in a culture in which cells are growing. After one cell division, you analyze the DNA and find all the DNA has some N15 in it. You then grow those cells for another generation in a […]

In the case of a locus with two alleles, P is the frequency of AA, H is the frequency of Aa, and Q is the frequency of aa. As with gene frequencies, genotype frequencies must sum to 1: P + H + Q = 1 Given a population having the […]
