module 6 patterns of inheratince

Question 1

homozygous

Answer 1

two of the same allele

Question 2

heterozygous

Answer 2

two different alleles

Question 3

codominance

Answer 3

both alleles are equally dominant
can be expressed together to form three different phenotypes

Question 4

sex linkage

Answer 4

characteristics determined by genes in sex chromosomes

Question 5

epistasis

Answer 5

when one gene is affects the expression of another gene
example gene coding for enzyme that prohibits another gene

Question 6

factors affecting evolution

Answer 6

mutation
sexual selection
gene flow
genetic drift
natrual selection

Question 7

allopatric speciation

Answer 7

new species formed when original population separated by physical barrier such as ocean

Question 8

sympatric speciation

Answer 8

new species formed by interbreeding
will have different numbers of chromones so they cant mate with either of parents species

Question 9

P (hardy Wienberg)

Answer 9

frequency of dominent allele

Question 10

Q ( hardy Wienberg)

Answer 10

frequency of recessive allele

Question 11

continuous variation

Answer 11

quantitative difference
polygenic inheritance (multiple alleles)
affected by enviorment

Question 12

discontinuous variation

Answer 12

qualitative difference
caused by one or two genes
affected by genetics
