14. (4) For a gene pair, there are four combinations of phenotypes: AB, Ab, ab, and ab. These occur in a ratio of 9:3:3:1 among F2 progeny.
a) What is the probability that a randomly selected individual from the F2 population will
have an AB phenotype?
b) What is the probability of selecting either an AB or Ab individual?
c) What is the probability of selecting an AB individual and an ab individual?
d) What is the probability of first selecting an aB individual first and then selecting an Ab
individual second?

Genetic diversity is the variation in the genes of an entire species. each circle represents a population of a particular species in different habitats. select the population with maximum genetic diversity

How will technology impact medicine in the future?

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.
