Ch 11 QUIZ 3 PRACTICE

1.

1 point

All of the following are true about making
a punnet square EXCEPT:

The inside of the square shows the possibility for children

It shows only phenotypes.

The outsides of the square show the parent's genotype.

It shows the possible egg and sperm combinations for a trait

2.

1 point

Versions (choices) for a trait, such as blue , green, brown, and hazel for eyes are called

genes

zygotes

alleles

genotypes

3.

1 point

Which statements about genetics is NOT TRUE:

There are dominant and recessive traits

The dad's traits are usually stronger

There are 2 genes for each trait - one from mom and one from dad

a person can have a gene in them for a trait that does not show up in them EX: a right handed person may have a gene for left-handed in their chromosomes

4.

1 point

Have two different genes from your parents, like Mm is called

homozygous recessive

heterozygous

heterozygous dominant

homozygous dominant

5.

1 point

Why don't two parents have all their children look the same?

It is all because of mutations each time

Because the eggs and sperm are all different combinations of their genes

Because our DNA changes during our life

Because all the eggs are the same, but all the sperm is different.

6.

1 point

What traits an offspring gets depends on

genes in both the sperm and egg

it has nothing to do with the eggs and sperm

genes only from the female’s egg

genes only from the male’s sperm

7.

1 point

The punnet square is best used to

show the probability or chances of having a child with certain traits

show the relationships of a family

show that everyone can have children with any trait

show how parents make gametes

8.

1 point

Which genotype below is heterozygous?

Hh

ee

BB and ee

BB

9.

1 point

T = tall and t = short

What is the genotype of a tall plant?

Tt and TT

T

tt only

TT only

10.

1 point

Which statement below is FALSE?

Two parents that are right handed (Rr) can have a left handed child (rr)

Two parents that are left handed (rr) can have a right handed child (Rr)

If R = right-handed , then r = left-handed

A right handed parent (Rr) can pass a left handed gene to his child if that sperm is the one to fertilize the egg
