Probability and Polygenic traits

Question 1

-What is probability
-probability formula
-2 rules of probability

Answer 1

-study of outcomes of events
-number of chances/number of possible
1. rule of independent events: chance has no memory and previous events have no effect on future
2. product rule: probability if seperate is the product of these events sperately

Question 2

Dihybrids can be treated as what?
-those can be combined to calculate what?

Answer 2

-2 monohybrids
-probabilities of a dihybrid cross

Question 3

-what are polygenic traits
-what is an epistatic gene
-what is a complimentary interaction?

Answer 3

-inherited traits that are affected by 2+ genes
-masks the expression of other genes
-then 2 different genotypes interact to produce a phenotype that is neither capable of producing itself
