Accepted Answer

Answer

Answer

Answer

traits

Question 2

Accepted Answer

proteins

Answer

Answer

Question 4

Why did Gregor Mendel use pea plants for his experiments on heredity?

Accepted Answer

Pea plants have easily observable traits, produce several generations in a year, and self pollinate.

Answer

Peas taste good and are easy to cook.

Answer

Pea plants look very lovely in the garden and produce beautiful flowers.

Answer

Peas are a good source of vitamin A, vitamin C, folate, thiamine, iron and phosphorus. They are rich in protein, carbohydrates, and fiber and low in fat.

Question 5

What is heredity?

Accepted Answer

The passing of traits from parent to offspring.

Answer

A family tree that shows the relationships between an organism and its ancestors.

Answer

A diagram that is used to predict the genotypes of offspring produced by two parents.

Answer

A notable feature or characteristic of an organism.

Question 6

When Gregor Mendel cross fertilized pea plants that had purple flowers with pea plants that had white flowers, the white flower trait disappeared in the offspring. This is because the purple flower trait is ___________________ over the white flower trait.

Accepted Answer

dominant

Answer

recessive

Answer

masked

Answer

hidden

Question 7

What did Mendel use to represent the "factors" pass on by parent to offspring?

Accepted Answer

Capital and lower case letters

Answer

Letters and numbers

Answer

Large and small numbers

Answer

A color scale

Question 8

In the Parent (or P) generation, Gregor Mendel cross fertilized pea plants that had purple flowers with pea plants that produced white flowers. In the F1 generation, all the plants produced purple flowers, but Mendel predicted that the white flower factor was still present hidden on the flowers. Mendel used the letters Pp to represent the factors that the F1 generation plants had for flower color. Which term is used to describe the genotype Pp?

Accepted Answer

Heterozygous

Answer

Homozygous dominant

Answer

Homozygous recessive

Answer

Heterogeneous mixture

Question 9

What does Homozygous dominant mean?

Accepted Answer

That both alleles for a gene are dominant, so the dominant form of the trait will be expressed.

Answer

That both alleles for a gene are recessive, so the recessive form of the trait will be expressed.

Answer

That one allele is dominant and one is recessive, which mean the dominant trait will be expressed in the offspring.

Answer

That no alleles are present.

Question 10

The hybrid seeds from the F1 generation pea plants were collected, planted, and then allowed to self-fertilize. Mendel called this generation the F2 generation. What ratio of traits did Mendel observe in the F2 generation?

Accepted Answer

3:1

Answer

1:1

Answer

2:1

Answer

4:1

Question 11

Which choice contains a group of traits from our class traits survey that also had very close to a 3:1 ratio?

Accepted Answer

Detached earlobes, tongue rolling, and naturally curly hair

Answer

Height, dimples, and detached earlobes

Answer

Dimples, allergies, and tongue rolling

Answer

Cleft chin, color blindness, and thumb crossing

Question 12

Mendel initially focused his experiments on manipulating one trait at a time. Eventually, Mendel expanded his experiments to include two traits at the same time, such as seed color and shape, in order to find out if having one trait affected having a second trait. Based on his results, what is the answer to this question? Do people with blonde hair have to have blue eyes?

Accepted Answer

No

Answer

Yes

Question 13

Which word means to be masked or hidden?

Accepted Answer

recessive

Answer

dominant
