Question

If a population of 1,000 individuals has 160 rr genotypes, what is the frequency of the rr genotype?

Please explain how you got the answer.

Answer 1

@jhonyy9

Answer 2

1000 ----- 160
100 ----- x
-----------------
x=(160*100)/1000 =16000/1000 =16

so this result mean that is 16%

Answer 3

ok ?

Answer 4

so just you need using the rule of 3 simples

Answer 5

thanks so much! would you mind helping me with one other type of problem? @jhonyy9

Answer 6

If a population of 1,000 individuals has 160 rr genotypes, assuming simple dominance by the A allele, what is the frequency of the dominant allele (R) in this population?

Please explain? @jhonyy9

Answer 7

@aaronq do you know this one?

Answer 8

i dont remember how to do this sorry

Answer 9

That's ok @aaronq

Answer 10

@hba @jazy do either of you guys know how to do this? I'm so lost.
My textbook makes it so confusing... I wish @jhonyy9 could explain this one again! :(

Answer 11

sorry but this one i dont undersatand it
the first one of your question was easy but this last with A allele ??? sorry

what mean this allele ? sorry but i dont understand it

Answer 12

What do you mean? @jhonyy9

Answer 13

A very large population of randomly mating laboratory mice contains 35% white mice. White coloring is caused by the double recessive genotype "aa." Calculate the frequency of the heterozygous genotype (Aa) in this population.

Do you understand this one?

Answer 14

so can you rewrite me how makes your textbook ? why is it for you ,,confusing" ?

Answer 15

I'm going to ask my teacher about it but she hasn't been answering... Do you understand how to do the other one I posted just now? @jhonyy9

Answer 16

moment please

Answer 17

100 ----- 35 white mice so what mean 35% ,,Aa"
so do you know how many is this large population ?

Answer 18

That was the only information given to me.
When you write 100 --------- 35 does that mean you're multiplying?

Answer 19

no

this you have wrote it above in your exercise 35% so this mean from 100 are white 35

ok ?

Answer 20

I don't really understand the way you're typing... Can you try to word it differently? @jhonyy9

Answer 21

My answer key says that the answer could be 47%, 48%, or 49%
How did they get that?

Answer 22

so above you have wrote that 35%white mice is from a laboratory very large population

and this is have wrote it that this 35% mean that from 100 mean 35 mice white

ok ?

Answer 23

Ok, I think I get that part. Now how do you get the answer of 47, 48, and 49 % ?

Answer 24

sorry but i not can getting these answers

i dont know sure this way

sorry

Answer 25

so this 49% if this is right --- so this mean approximatly a half part of this population

Answer 26

yes, i think..

Answer 27

so than i dont know what is the way to get these answers you need to ask your teacher

sorry

Answer 28

Ok, can you try to help me with just one more?

In corn, the allele for yellow coloring has complete dominance over the allele for white coloring. A random sample of 1,000 kernels from a population that is in equilibrium reveals that 910 are yellow and 90 are white. What is the percentage of heterozygotes in this population?

The answer is .42 or 42. How did they get this??

Answer 29

sorry

good luck

bye

Answer 30

Ok...
