Genetics

Question 1

Gregor Mendel was a

Answer 1

monk/botanist
- father of genetics

Question 2

Why were pea plants used

Answer 2

• hybrids could be produced
• variations available
• small and easy to grow

Question 3

pea plant fertilization included

Answer 3

self and cross fertilization

Question 4

self fertilization

Answer 4

flower from pea plant can fertilize that same plant

Question 5

cross fertilization

Answer 5

siblings from same generation can cross fertilize

Question 6

Mendel law 1

Answer 6

allele separation

Question 7

allele separation

Answer 7

2 alleles separate during gamete formation and are rejoined at random

Question 8

Mendel Law 2

Answer 8

independent assortment

Question 9

alleles are inherited

Answer 9

randomly (even recessive)

Question 10

Monohybrid cross

Answer 10

cross to study 2 variations of a single trait

Question 11

dihybrid cross

Answer 11

examination of 2 separate traits in a single cross

Question 12

genotype

Answer 12

total set of alleles of an individual

Question 13

Genotype examples

Answer 13

PP- homo dom
Pp- hetero
pp- homo recess

Question 14

phenotype

Answer 14

outward appearance of an individual

Question 15

probability =

Answer 15

of times an event occurs/ # of possible outcomes

Question 16

product rule

Answer 16

prob that 2 or more independent events will occur

Question 17

testcross

Answer 17

a cross used to determine the genotype of an individual with dominant phenotype
- use homo recess

Question 18

polygenic inheritance

Answer 18

occurs when multiple genes are involved in controlling the phenotype of a trait

Question 19

incomplete dominance

Answer 19

heterozygote is intermediate in phenotype between the 2 homozygotes

Question 20

recombination frequency

Answer 20

recombinant progeny/ total progeny

Question 21

< 50% recombinance

Answer 21

means they are on the same gene

Question 22

smaller %

Answer 22

means closer together
