Aresearcher is studying a newly discovered gene that causes increased body weight in domesticated chickens. in a mainland population, the frequency of the a1 allele is 0.2, for this gene with two alleles. if 100 of these mainland chicken are transported on a ship to an isolated island with a population of 200 a1a1 chickens, 400 a1a2 chickens, and 400 a2a2 chickens, what would the frequency of the a1 allele in the admixed population?

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
