What term describes this process occurring in Prophase I?
a

d
independent assortment
Question 34
Mendel called plants that received different alleles for a trait from each parent _________________ .
a
hybrids
b
recessive
c
purebred
d

Question 35
When you cross two heterozygous organisms what is the probability that the offspring will show the dominant phenotype? (HINT: You may want to draw a Punnett Square on a separate piece of paper to help.)
a
4/4
b
3/4
c
2/4
d
1/4
Question 36
A farmer is breeding two different types of plants with varying patterns of inheritance. For Plant Type A, the allele for red petals is (R) and the allele for white petals is (r). The farmer crosses a homozygous red plant with a homozygous white plant. For Plant Type B, the alleles for both red (R) and white (W) petal color are dominant. The farmer crosses a homozygous dominant red plant with a homozygous dominant white plant. The results of the farmer's crosses are shown in the Punnett squares.
What are the inheritance patterns for each of the plant types?
a
Plant Type A shows a codominance pattern of inheritance, and Plant Type B shows an incomplete dominance pattern of inheritance.
b
Plant Type A shows a recessive pattern of inheritance, and Plant Type B shows a complete dominance pattern of inheritance.
c
Plant Type A shows a complete dominance pattern of inheritance, and Plant Type B shows a recessive pattern of inheritance.
d
Plant Type A shows an incomplete dominance pattern of inheritance, and Plant Type B shows a codominance pattern of inheritance.
Question 37
Based on the information in this table, which men could not be the father of the baby?

a
George
b
Sammy
c
The waiter
d
The cable guy
Question 38
Incomplete dominance is shown in the fruitloop flower, WW are white, RR are red and WR are pink.
Use scratch paper to set up a Punnett square for a cross of the F1 generation (pink flowers).
What is the percentage of pink flowered offspring in the F2 generation of two pink flowering fruitloop plants?
a
100% pink
b
75% pink
c
50% pink
d
25% pink
e
no pink
