Question 1

Punnett Square

Answer 1

a chart that shows all the possible combinations that can result from a genetic cross.

Question 2

An Uppercase letter represents

Answer 2

dominant allele

Question 3

Lowercase letters represent

Answer 3

a recessive allele

Question 4

Homozygous/Purebreds

Answer 4

must have 2 of the same alleles

Question 5

Heterozygous/Hybrids

Answer 5

Heterozygous/Hybrids

Question 6

Trait

Answer 6

A physical characteristic

Question 7

Purebreds

Answer 7

always produce offspring with the same form of a trait as its parent.

Question 8

Nucleolus of cell: Put in order

Chromosome, nucleotide, gene. cell

Answer 8

Cell, Chromosome, Gene, nucleotide

Question 9

Codominance

Answer 9

neither of the alleles is dominant or recessive. Both alleles are expressed in the offspring.

Question 10

incomplete dominance

Answer 10

the trait is a blend of both phenotypes. For example, a red flower and a white flower would produce a pink flower.

Question 11

The Genetic Code:

Answer 11

The order of nitrogen bases along a gene forms a genetic code.

Question 12

The sides of the DNA molecule are made up of?

Answer 12

phosphates and deoxyribose.

Question 13

Nitrogen Bases:

Answer 13

Thymine – Adenine,
Cytosine – Guanine

Question 14

Nucleotide:

Answer 14

A deoxyribose, a phosphate, and one nitrogen base

Question 15

double helix

Answer 15

shape of DNA

Question 16

Who is the “father” of DNA

Answer 16

Gregor Mendel

Question 17

Asexual reproduction

Answer 17

Offspring have 100% the same chromosomes as the parent.
Most unicellular organisms reproduce this way.

Question 18

Types of asexual reproduction:

Answer 18

Budding is a means of asexual reproduction whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently.
Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts. Regeneration occurs via mitosis. Lizards can regenerate their tails, starfish can regenerate their arms
Binary fission is a form of asexual reproduction where every organelle is copied and the organism divides in two.
Vegetative reproduction when plants develop from modified stems or roots, or plantlets

Question 19

Sexual reproduction:

Answer 19

Organisms that reproduce through sexual reproduction are multicellular organisms like animals and plants. Sexual reproduction requires 2 parents and the offspring or babies get half their genetic information from each parent. Offspring or babies will look similar but will NOT be an exact copy of their parents. They are a blend of each parent’s traits.

Question 20

Heredity

Answer 20

The passing on of traits from parent to offspring

Question 21

Innate Behavior

Answer 21

A behavior known from birth
Example: humans breathing

Question 22

Learned Behavior

Answer 22

A behavior that develops through experience or practice. ex: bird learning to fly
