unit 4

Question 1

heredity

Answer 1

the study of patterns

Question 2

phenotype

Answer 2

the trait that you see

Question 3

genotype

Answer 3

the actual gene

Question 4

complete dominance

Answer 4

one allele completely masks the other

red+white=red

Question 5

codominance

Answer 5

neither alleles mask each other resulting in a blend of both, red+white=pink

Question 6

incomplete dominance

Answer 6

neither alleles mask each other resulting in a bit of both.

red+white= red/white

Question 7

independent assortment

Answer 7

some genes are separate and will not affect each-other,

green eyes ≠ brown hair

Question 8

segregation

Answer 8

the equal separation of two alleles
Bb
/ \
B b

Question 9

is a trait a phenotype

Answer 9

no

Question 10

diploid

Answer 10

2 chromosomes per trait

Question 11

haploid

Answer 11

1 chromosome per trait

Question 12

is a characteristic a phenotype

Answer 12

no

Question 13

is a characteristic a variation

Answer 13

yes

Question 14

gene

Answer 14

a sequence of DNA that codes for a protein

Question 15

allele

Answer 15

a different variation of a gene

Question 16

relationship between a gene and a chromosome

Answer 16

genes are segments of chromosomes

Question 17

a bell shaped curve

Answer 17

multiple factors are going to be affecting it

Question 18

asexual reproduction vs sexual

Answer 18

Asexual reproduction involves only mitosis and results in a genetic clone of the progenitor while sexual reproduction involves both mitosis and meiosis and results in a similar but ‘upgraded’ version

Question 19

Meiosis steps

Answer 19

Prophase I
Metaphase I
Anaphase I
Telophase I
Prophase II
Metaphase II
Anaphase II
Telophase II

Question 20

Blood types

Answer 20

A, AB, B, O

what is the chance of flipping a coin 3 times and landing heads, after two flips landing on heads, what is the chance the next flip will be heads?

Answer 21

1/8, 1/2

using the same information (red>blue) do the cross between two heterozygous red

Answer 23

75% red

50% Rr
25% RR
25% rr

Question 24

red is codominant to blue (purple)

cross of a red and a blue

Answer 24
