Question 10

A Punnett square showing the cross between two pea plants is shown. In pea plants, the smooth coat allele (R) is dominant over the wrinkled coat allele (r). One part of the Punnett square is filled in. Which shows the correct letters and pictures for the peas that should be in the other 3 squares.

Accepted Answer

Option B is correct

Answer

A.

Answer

C.

Answer

D.

Question 11

Two brown-eyed parents can produce a child with blue eyes. Which of the following best explains how this is possible?

Accepted Answer

The genes passed on by the parents can combine in a new way in the child.

Answer

Blue eyes are an adaptation that can help the survival of humans.

Answer

Over many generations some characteristics become more frequent.

Answer

Eye color is always a mixture of the traits of both parents.

Question 12

A complete Punnett square here shows a cross between two mice with different fur color, agouti (A) and black (a). This Punnett square can be used to make which of the following conclusions?

Accepted Answer

The trait of agouti fur is dominant over the trait of black fur.

Answer

Two agouti mice can't produce offspring with black fur.

Answer

Eventually, all the mice that descend from this pair will have black fur.

Answer

The trait of agouti fur is an advantage to mice for avoiding predators.

Question 13

You can tell a difference between the offspring of sexually reproducing organisms from the offspring of asexually reproducing organisms by studying which of the following?

Accepted Answer

The amount of variety in the genetic information in the population of offspring.

Answer

The average amount of time involved between fertilization and birth of the offspring.

Answer

Comparing sizes in height of the organisms when they reach adulthood.

Answer

The diet and habitat requirements for each individual organism.

Question 14

Which of the following is true? Any individual offspring produced through asexual reproduction is always:

Accepted Answer

genetically identical to its parent.

Answer

made up of cells with a cell wall.

Answer

different from all of its siblings.

Answer

very slow to develop and grow.

Question 15

Which of the following is true? If an offspring is produced through sexual reproduction, the offspring's genetic material is always:

Accepted Answer

a blend of the genetic material of its parents.

Answer

an identical copy of the father.

Answer

an identical copy of the mother.

Answer

very slow to develop and grow.
