1. A plant with purple flowers is allowed to self-pollinate. Generation after generation, it produces purple flowers. This is and example of
a. hybridization
*has nothing to do with making a hybrid
b. incomplete dominance
c. true-breeding
d. the law of segregation
*nothing is separated
e. polygenetics
*(using root) many genes, doesn't sound like it
I'd narrow it down to B or C

15. The couple decides to have a second child.What is the probabiility that this child will be albino?
a. 0
b. 1/4
c. 1/2
d. 3/4
e. 1
*If it's dominant, 3/4, if recessive, 1/4

22. Black fur in mice (B) is dominant to brown fur (b). Short tails (T) is dominant to long tails (t). What fraction of th progeny of the cross BbTt x BBtt will have black fur and long tails?
a. 1/16
b. 3/16
c. 3/8
d. 1/2
e. 9/16
*make some Mendelian crosses, I'd eyeball it as being E since it's two dominants

23. A couple has three children, all of whom have brown eyes and blood hair. Both parents are homozygous for brown eyes (BB), but one is a blond (rr) and the other is a redhead (Rr). What is the probability that their next child will be a brown-eyed redhead?
a. 1/16
b. 1/8
c. 1/4
d. 1/2
e. 1
*again, Mendelian crosses

34. A woman has six sons. The chance that her child will be a daughter is
a. 1
b. 0
c. 1/2
d. 1/6
e. 5/6
*Don't remember
33. The probablility that four coins will come up heads when flipped simultaneously is
a. 1/4
b. 1/2
c. 1/8
d. 1/16
e. 1/64
*I believe D, 2^4

69. A man who carries an X-linked allele will pass it on to
a. all of his daughtrs.
b. half of his daughters.
c. all of his sons.
d. half of his sons.
e. all of his childeren.
*also don't remember
