Document Summary

Pass essentially unmanaged from one generation to the next. Physical appearance and biochemical properties of the organism. Undergo mutation to allow variation that leads to adaptation a rediscovery of mendel. Discovery of the genetic material a outline chromosome theory and composition. Mendel chromosome ( mostly little protein nucleic acids. Protein really complicated , 20 amino acids the complexity of life would be best captured with more complex molecules. Very simple , only 4 nucleotides don"t know the structure of dna yet. Dna is the hereditary material: streptococcus pneumonia.

Assume a population of pea plants consists of 300 TT and 700 tt, with T (tall) dominant to t (short).

A. What are the phenotypic, genotypic, and allele frequencies?

B. Further assume that you allow this population to undergo one generation of random mating with eachother and you know that mutation is very rare, there is no selection happening, and the population is large enought that drift is negligible. You count the number of tall plants to be 382 and the number of short plants to be 368. What is the genotypic frequency of this generation? What is the allele frequency?

C. Was the original population in Hardy Weinberg equilibrium?

D. Did any evolution occur from one generation to the next?

	1 The genetic make-up of apopulation gradually changes from one generation to the next.
	2 Living organisms change overtime.
	3 Each species produces many moreoffspring than can survive long enough to reproduce. The offspringthat do survive contain genes that are inherited from theparents.
	4 There is variation among themembers of a species. Some of this variation is geneticallydetermined and so can be passed on to future generations.
	5 Some individuals have genes thatincrease their chances for survival and reproduction. Theseindividuals are more likely to reproduce and pass on their genes,causing their genes to become more common in the nextgeneration.
	6 There is a struggle for existenceamong the members of a population.
