Flashcards in Lecture 3 Deck (10):
Probability of rolling a 4 twice in a row?
Probability of rolling a 3 or a 4?
If probability of being blood type A is 1/8 and the probability of blood type O is 1/2 what is the probability of being type A or O?
The probability of an event A, given that event B has already occurred
A cross btw 2 heterozygous parent plants. What is probability that a tall offspring plant is homozygous?
Tt X Tt = 1/4 TT + 1/2 Tt + 1/4 tt
BUT tt cannot take place bc looking ONLY at tall offspring plants
= 1/3 TT + 2/3 Tt
Probability that tall offspring will be TT = 1/3
p=freq of one outcome
q=freq of another outcome
n=number of events
Review lecture 3 slide 34 (albinism/binomial expression)
Di hybrid cross
Examining two traits at same time
What principle do di hybrid crosses reveal?
Principle of independent assortment
In a dihybrid cross, would crossing over change the relationship of the 2 diff genes in the offspring?
No, traits on diff chromosomes will sort independently
