Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

2) The Hardy-Weinberg principle tells us what to expect when a sexually reproducing population is

a.not evolving

b.increasing in size

c.changing in size

d.evolving

e.not evolving under natural selection specifically

Definition Definition Principle that states that allele and genotype frequencies in any population will remain constant from one generation to another in the absence of other evolutionary forces. The Hardy-Weinberg principle is used for testing genotype frequency for population stratification and other non-random mating forms.

Humans often kill rattlesnakes that they encounter. Rattlesnake populations close to human habitation thus experience higher adult mortality rates. As Dr. Beck has found in his research on Northern Pacific Rattlesnakes in Washington state, these populations tend to evolve a shift toward more "r-selected" life-history strategies, such as (select all that apply): Smaller size at first reproduction. Early age at first reproduction. O More extensive parental care. O A few large offspring per reproductive event. Lots of small offspring per reproductive event.
