Which statement below is FALSE?
A right handed parent (Rr) can pass a left handed gene to his child if that sperm is the one to fertilize the egg
Two parents that are right handed (Rr) can have a left handed child (rr)
If R = right-handed , then r = left-handed
Two parents that are left handed (rr) can have a right handed child (Rr)
T = tall and t = short
What is the genotype of a tall plant?
Tt and TT
Which genotype below is heterozygous?
BB and ee
The punnet square is best used to
show the probability or chances of having a child with certain traits
show how parents make gametes
show that everyone can have children with any trait
show the relationships of a family
What traits an offspring gets depends on
genes in both the sperm and egg
genes only from the male’s sperm
it has nothing to do with the eggs and sperm
genes only from the female’s egg
Why don't two parents have all their children look the same?
Because our DNA changes during our life
It is all because of mutations each time
Because the eggs and sperm are all different combinations of their genes

Versions (choices) for a trait, such as blue , green, brown, and hazel for eyes are called
All of the following are true about making
a punnet square EXCEPT:
