Mendel crossed a true-breeding plant that produced green seeds with a true-breeding
plant that produced yellow seeds to produce an f1 generation. the entire f1
generation produced yellow seeds. then he crossed the f1 offspring with each other to
produce the f2 generation. from the f2 generation, he counted 6022 yellow seeds.
which of these is the most likely estimate of the number of green seeds he collected
from the f2 generation?
a. 0
b. 2000
c. 6000
d. 18000

in a test cross, if one parent’s genotype is homozygous dominant,
a. all of the offspring will have the dominant phenotype.
b. 3/4 of the offspring will have the dominant phenotype.
c. 1/2 of the offspring will have the dominant phenotype.
d. 1/4 of the offspring will have the dominant phenotype.

the base-pairing rule for binding purines and pyrimidines in the dna molecule is
a. c-u and a-g.
b. a-g and c-t.
c. a-t and c-g.
d. c-a and g-t

. the small segments of the lagging dna strand are called
a. helicase.
b. nucleotides.
c. okazaki fragments.
d. hershey bits.
