VCE Biology: Survey for Assessment

[caffinatedloz]

Hey guys! For my bio class, I need to conduct a survey about attitudes towards an ethical issue surrounding the "Warrior Gene". It would be super great if you guys have a minute to fill it out. It only has four multiple choice questions and then two optional written questions.

Thanks so much!!

great interesting questions on the survey @laura_

found this one error though, 'As it is carried on the X chromosome, it affects men more severely than women.'

Y chromosome?

Nah Laura meant what she said.

People born with XX chromosomes are likely to be less impacted by a gene-variant/allele present on X chromosomes than people with XY chromosomes. This might seem counter intuitive, but if someone only has 1 X chromosome they're likely to be more impacted by a gene on that than if they have 2 X chromosomes (since one of the chromosomes might not have that gene variant).

Hope this makes sense!

oh lol
This goes against everything I've learnt in unit 2 bio,
hard to wrap my head around but makes sense

thnx Bri

Have you done any pedigrees with X-linked recessive genes? That might help you understand it a little more. Because with these traits, far more men have them than women, and all women will have fathers and sons with the trait.

To clarify:

For all women who display the trait each of their fathers and sons will display the trait

If they're a carrier you would only expect 50% of male offspring to display the trait (which might result in none of their sons having the trait)

If they don't have any copies of that allele their father won't display the trait.

Thanks Bri!

And adding on to that, with X-linked traits, only women can be carriers. (Men cannot as they only have one X chromosome and so either their chromosome has the allele or it doesn't.)
