Probability & Punnett Squares
100 Probability
what is most likely to happen
200 If a family has five sons and three daughters.
What is the probability that the next child will be a female?
1 in 2 or 50:50 or 50%
300 what # of trials will be closest to the expected probability:
10,000
10,100,1,000, 10,000

none
Genetics Concepts
100 definition of a polygenic trait
200 definition of a codominant trait
300 an example of a multiple allele trait
400 an example of incomplete dominance
500 an example of a sex-linked trait
influenced by genes on more than one chromosome
has two alleles that are both dominant & will both show if
present
