AQA AS Biology Unit 2 - 1 June 2015

It was 33:1
Because you divide whole US population by the number of the people who have the disease.
Do the same for the island people.
Then divide the two numbers together 10600/300

Oh no

and yeah, I got 2.68 for diversity. I feelss like I'd have got the same grade if I didn't turn up!

Did u have to right about semi conservative in the 2 genetically identical cells in interphase and mitosis, i just talked about PMAT

Hi, I think it was 32:1, my friends got that too.

i got 0.31:1. how can you get 32:1 for america when the the other place had a larger chance of inheriting the allele?

I took into account the populations of each and got a ratio in terms of 1 being not america. So i got 0.00.. something to 1

App u had to say due to semi conservative replication the 2 cells are identical

because if you read the question (it was misleading) 1 represented the 3000 population size and you were to work out america.

The question asked about number of people in the population with colour blindness, so although there was a higher chance in the other country, USA had a much higher population so overall more people did have the colour blindness gene. That's how I understood the question anyway!

Semi conservative replication is dna replication not mitosis so i doubt it
