Homework Answers

Answer #1

The correct option is D.natural selection and mendelian genetics.

Natural selection and mendelian genetics are major concept in biology were unified in the middle of the twentieth century. The modern synthesis was the early twentieth century synthesis, which unified Charles Darwin's theory of evolution and Gregor Mendel's ideas on heredity. The 19th century thoughts of natural selection and Mendelian genetics were arrange with population genetics in the twentieth century.

Background: Darwinism Today the theory of evolution is a well-supported, unifying principle in biology, which explains how life on earth began and developed. The scientific evidence overwhelmingly supports the idea that all living things share a common ancestry. Charles Darwin, a British naturalist, is the person most remembered for his contribution to how the process of evolution works. He wrote a book, published over 150 years ago, called On the Origin of Species, which was very controversial at the time....

) Imagine that you are a grad student in Biological Anthropology, and you travel to the land of “Jenesaiquoivia” to study Jenesaiquoivian genetics. [Footnote 1] You notice that 9 out of every 100 people in your study group have blue eyes. The rest of the population have brown eyes. You know that the brown eyes allele is dominant, and blue eyes is recessive. [2] Construct the Hardy-Weinberg equation for that population. You know that q2=.09 (9%) so p2 plus 2pq...

B) A modern-day extinction, as is occurring today due to climate change, will probably result in a loss of biodiversity rather than a new explosion of diversity as occurred in the...
