Population genetics

Question 1

Darwin and Wallace (1859)

Answer 1

Evolutionary theroy

speciation occurs through natural selection

Question 2

Mendel (1850s/60s)

Answer 2

principles of genetics

hereditary occurs through trnasmission of alleles

Question 3

The modern synthesis

Answer 3

population genetics

natural selectrion acts within populations by changing allele frequencies

Question 4

parents

Answer 4

contribute to a pool of gametes

Question 5

gametes

Answer 5

fertilise one another

Question 6

zygotes

Answer 6

become parents of the next generation

Question 7

calculating allele frequencies from genotype frequencies

Answer 7

each diploid invidivual has two copies of the same gene

an individual can be homozygous or heterozygous

i swear it’s just the hardey weinberg principle- p squares + 2pq + q squared= 1

Question 8

harvey weinberg

Answer 8

in a large randomly mating population- fixed relationship between gene and genotype frequencies

absense of selectrion or other disturbing influences

Question 9

if there are frequency changes then….

Answer 9

the population may be- undergoing natural selection, mating non-randomly, losing alleles through random genetic drift, undergoing mutation, migration (?)

Question 10

assumption one of the HW

Answer 10

there is no net migration

Question 11

second assumption of the HW

Answer 11

population is large

Question 12

whats another assumotion of the HW (3rd)

Answer 12

mating is random with respect to allele A

Question 13

assumtion 4

Answer 13

no natural selection

Question 14

aummption 5

Answer 14

no net mutation
