Two closely related populations of squirrels become separated after a large river permanently changes course. Thousands of generations later, the two populations can no longer produce fertile offspring. This is an example of speciation. In a different population of flowering plants, a chromosome mutation immediately prevents some individuals from successfully reproducing with the rest of the population, even though they continue living in the same location. This is an example of speciation. Both blanks are ONE word.

Discuss the human example of Founder Effect that was presented at length in lecture. Name one consequence of Founder Effect in this population (can be general), and how founder effect alters genetic diversity of a population.

is the only force of evolution that generates new variation.

Mendel’s Law of Independent Assortment remains an important principle in genetics, but the lecture explained that it is not entirely accurate. Why is this law not always true?

In a population of 1,000 individuals, 16% exhibit a recessive phenotype for a simple Mendelian trait. Assume the population meets Hardy-Weinberg expectations. Recall the two Hardy-Weinberg equations: p + q = 1 p2 + 2pq + q2 = 1 As we learned, each of those variable components represents something, which you should remember or have in your notes. What is the value of p2? I have input the 0 and the decimal for you, just type a whole number.  p2 = 0. What is the value of q? I have input the 0 and the decimal for you, just type a two-digit number.  q = 0. What is the value of p? I have input the 0 and the decimal for you, just type a two-digit number.  p = 0. What percentage of the population is expected to be heterozygous? Just write a whole number. % heterozygous = %

Early biological anthropologists often referred to the field as physical anthropology, but today the field is more commonly called biological anthropology. According to the lecture, what was a major reason for this change?

James Hutton and Charles Lyell argued that the slow geological processes they observed operating today could also explain ancient rock formations and Earth’s history. This perspective became known as .
