Week 1, week 2, If A and B are mutual exclusive events, the probability one of them occur, P(A or B) is

Complementation

2 or more genes necessary to give a function, if they compliment they are different genes.

If A and B are mutual exclusive events, the probability one of them occur, P(A or B) is

P(A+B)=P(A)+P(B)

incomplete dominance

Situation in which one allele is not completely dominant over another allele

sum rule

for two exclusive events the probability of either occurring is the sum of them both

multiple alleles

three or more forms of a gene that code for a single trait

Mendel's 2nd Law of Independent Assortment

allele pairs seperate independently during the formation of gametes

Mendel's 1st Law of Segregation

1. characters are determined by particulate factors 2. Factors exist in pairs of each organism a. one parent transmits one member of a pair to an offspring; therefore they "segregate" b. a progeny gets one factor from its father and has a pair of factors

Codominance

A condition in which neither of two alleles of a gene is dominant or recessive.

What are the possible gametes produced by F1 peas?

YR, yR, Yr, yr

product rule

if two events are independent the probability of both occurring is the product of each of them occurring
