1. Two true breeding parents are crossed similar to Mendel's P generation. A tall plant is crossed with a short plant. What is the expected outcome for the F1 generation?
all short
all tall
all medium height
half tall, half short

2. If the cross from #1 is continued, what would be the expected outcome in the F2 generation?
all short
all tall
3 tall, 1 short
half tall, half short

RR
Rr
rr
RrWw

4. This principle states that alleles separate during gamete formation:
principle of multiple alleles
principle of dominance and recessiveness
principle of independent assortment
principle of segregation

all
half

Pp x pp
Pp x Pp
PP x pp

9. In each case where Mendel crossed true breeding plants as parents, the offspring displayed only one of the two traits seen in the parents. This observation supports which principle of genetics?
segregation
independent assortment
dominance and recessiveness
allele frequency
