isolation and speciation

Question 1

what is speciation

Answer 1

the evolution of new offsprings from existing ones,

Question 2

how is speciation formes

Answer 2

through reproductive separation followed by genetic change due to natural selection

Question 3

what is adaptive radiation

Answer 3

change in allelic frequency and genetic makeup within a population too different population will not be able to breed to produce fertile offspring

Question 4

what is genetic drift

Answer 4

in small population there are fewer members of te population with a smaller variety of the alleles , few individuals breed and the alleles are restricted to the few alleles in the population .
as there are only few different allels those passed on will quickly affect the whole population thus mutation to thos alleles selectively favoured will impact the whole population

Question 5

what is allopratic speciation

Answer 5

speciation due to geographical separation

Question 6

what happens to the individuals on either side

Answer 6

they are reproductively separated as they cannot breed together between either side

Question 7

what will happen overtime

Answer 7

due to different selection pressures on either side and mutation lead to difference in allele best adapted to the environment and more likely to survive and pass on advantageous allele to offspring and increase and change allelic frequency

Question 8

what does this lead to

Answer 8

adaptive radiation as the differences in allelic frequency means they cannot breed to produce fertile offsprings

Question 9

wha is sympatric separation

Answer 9

reproductively separated occurs in the same population and same area resulting in different genetic differences
