Question 9

There are two different alleles for flower color, P and p. The image shows a white sweet pea that is labeled with its two alleles for petal color.

What can you surmise from the labeled image?

Accepted Answer

White petal color is a recessive trait.

Answer

The genotype is heterozygous.

Answer

White petal color is a dominant trait.

Answer

The phenotype is heterozygous.

Question 10

There are two different alleles for flower color, P and p. The image shows a purple sweet pea that is labeled with its two alleles for petal color.

Which is the genotype of the sweet pea?

Accepted Answer

homozygous dominant

Answer

heterozygous dominant

Answer

heterozygous recessive

Answer

homozygous recessive

Question 11

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower. What will the ratio of purple to white be?

Accepted Answer

3:1

Answer

1:3

Answer

2:2

Answer

4:0

Question 12

If you cross a black chicken with a white chicken, only black and white checkered chickens would be produced. What kind of inheritance pattern does this follow?

Accepted Answer

Codominance

Answer

Incomplete dominance

Answer

simple dominance

Question 13

In chickens, feather color is codominant. If a white chicken (WW) is mated with one that is black and white checkered (BW), what are the chances of having offspring that are black and white checkered (BW)?

Accepted Answer

50%

Answer

0%

Answer

25%

Answer

100%

Question 14

Which is a true statements about this picture?

Accepted Answer

Brown is dominant

Answer

Brown is recessive

Answer

Blue is dominant

Answer

Blue is codominant

Question 15

What are the possible phenotypes in this punnett square?

Accepted Answer

purple, white

Answer

Bb, bb, BB

Answer

Bb, bb

Answer

light purple

Question 16

What did Gregor Mendel use to study heredity?

Accepted Answer

Pea Plant

Answer

Pigeons

Answer

Pear trees

Answer

Photosynthesis

Question 17

Gregor Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). All the resulting offspring were tall. From these results, what conclusion did Mendel draw?

Accepted Answer

Tallness is a dominant trait.

Answer

The word homozygous always means dominant.

Answer

Only dominant alleles are passed on to offspring.

Answer

The alleles of the offspring were recessive.

Question 18

What is Mendel's Law of Independent Assortment?

Accepted Answer

The passing of allele of one trait does not affect the passing of allele of another trait.

Answer

If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

Answer

If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.

Answer

If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
