AP Biology 1.5 Evolution. What percentage of the population will show the dominant trait, S?


Transcript

00:00

Thank you and here's your shmoop du jour brought to

00:05

you by recessive traits because your brother had to get

00:08

his freaky webbed toes from well somewhere Okay here's Our

00:12

question In a population exhibiting hardy weinberg equilibrium twenty five

00:17

percent of the population shows a recess of trait S

00:21

what percentage of the population will show the dominant trait

00:24

i guess And here is a potential answers over Well

00:31

equilibrium is important in genetics in competitive games of jenga

00:35

in charlie sheen's a mental state way don't recommend putting

00:39

those last two together though that game still gives us

00:41

nightmares about hardy Weinberg states that gino type frequencies remain

00:46

constant in a generation when there aren't outside genetic influences

00:52

According to this model p the frequency of the dominant

00:56

eliel and cue the frequency of the recess of eliel

01:00

must add together the equal one under hardy weinberg You're

01:04

either dominant or your recess if there's no freaky third

01:07

off though seriously where'd he get those toes from that

01:11

ain't normal So assuming we're all able to subtract things

01:15

from one we can use these highly advanced mask eels

01:18

and subtract point two five twenty five percent from one

01:22

that gives us seventy five percent which means the correct

01:25

answer is d a happy ending for everyone except maybe

01:29

for your brother on the bright side if there's ever

01:31

a live action version of flipper well we'll know who 00:01:33.879 --> [endTime] to call
