Question

The gene for a widow's peak is dominant. A child inherits genes with the genotype: Ww and Ww. What are the chances that he will have a widow's peak?

25% chance
50% chance
75% chance
100% chance

Answer 1

@brynncess2003

Answer 2

well if is dominant than what would happen if the child is heterozygous

Answer 3

um i think c?

Answer 4

oh... i dont know.... @godmod360

Answer 5

oh... i dont know.... @godmod360

Answer 6

well since the trait for widows peak is dominant if the uppercase W is at all present than widows peak will be expressed meaning the if the genotype was WW or Ww it would be expressed and show

Answer 7

the child inherited genotype Ww and Ww
so doing the table shows
one WW
two Ww
and one ww

Answer 8

what does this tell you?
the question is saying that the widow trait is 'dominant'

Answer 9

..... 75%..... im sorry.... i get so confused with this stuff

Answer 10

thats what i think

Answer 11

yeah, i just dont get this stuff, yall are so smart compared to me

Answer 12

LOL

Answer 13

thats understandable bio can get genuinely confusing the important part id just ti try to understand as much as you can and in the end seek help if you need it.

Answer 14

im just gonna choose 75%

Answer 15

na
we are not as smart, just keep studying & learning
just know this

when your trait is 'recessive'
WW = will be not be effected because this feature is dominant
Ww = will be not be effected but will be a carrier of gene (if its disease), thats because dominant trait is expressed over recessive trait. In other words, recessive trait is silenced by dominant trait
ww = now this will be effected

if your trait is 'dominant'
WW = effected
Ww = effected, in this case it is effected because the trait is dominant, which is why its expressed over recessive w
ww = not effected

note it down somewhere
it helps a lot in these

Answer 16

thank you guys though

Answer 17

so yeah it is indeed gonna be 75%

Answer 18

yaya i was right!!

Answer 19

yyyaaayyyy!!! thank you!!!!!

Answer 20

ur welcome

Answer 21

yeah u were but @brynncess2003 can you please not give direct answers? its against CoC rules, so might get warning for that. Just explain how you do it & lead the questioner to correct conclusion, that will be a real help & will benefit them :)

Answer 22

oh yheah sorry!

Answer 23
