Back
22
C5-100-The answer is…
What is the phenotypic ratio of a
dihybrid heterozygous cross?
9:3:3:1
Back
23
C5-200-The answer is…
An organism’s gametes have ____ the
number of chromosomes as body cells
do.
half
Back
24
C5-300-The answer is…
Why is hemophilia more common in
men than in women?
It is sex linked so men only have to
have one allele while women must
have two.

pollination and cross pollination?
Self – fertilized by the same plant
Cross – 2 sets of genetic info are
crossed (different plants)
Back
27
Final Jeopardy

whether an organism is homozygous or
heterozygous for a trait?
