25%

Jacob's white and black dog had 4 puppies. Three of them had solid black coats and one was white and black like the mother. Which color coat is dominant?
Black
300
In pea plants, round and yellow are dominant traits, and wrinkled and green are recessive traits. What possible genotypes could give you a yellow, round pea plant.
RRYY or RrYy
300
Which cell cycle contributes to genetic variation in animal offspring?
Meiosis
400
What is the name for G1, S, and G2 phases? (hint: first phase of the cell cycle)
Interphase
400
Mitosis makes _____ cells, and meiosis makes ______ cells.
somatic, reproductive
also acceptable (body cells, gamates)

Pea seed pods can either be green (GG) or yellow (gg). When crossing a homozygous recessive parent with a heterozygous parent what are the percentages of possible phenotypes of the offspring?
50% green, 50% yellow
400
R = purple
r = yellow
T = tall
t = short

Set up a cross between a homozygous recessive parent and a heterozygous dominant parent. What is the probability of having offspring that is yellow and short?
25% probability or 1/4
400

XbXb
500
What is the cellular process that telophase occurs?
mitosis
500
Please draw the phase Telophase on the board.
answer should looks like 2 cells still attached and have two nucleus'
500
Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems? (phenotypic ratio)
3:1 hairy to hairless
75% hairy and 25% hairless also acceptable

Type A blood
Type AB blood
Type B blood
