Hi guys, I was wondering how you guys would answer this. Inbreeding within a population is likely to lead to:

1) an increased number of mutations
2) an increased expression of recessive traits

I think it should be 2, but I just wanted to confirm. I know inbreeding increases the chances of genetic disorders, but I don't know if they should be classified as "mutations". Thanks!

Pretty sure its #2 only. I don't see how expression of recessive traits is considered a mutation. But I could be wrong!

Any other takers?...

Yeah it should be #2

Thanks guys!

Chapel, did you end up redoing the DAT? If not, how's the prep coming along?

i would say #2 as well. Reproduction would favor an increased in variability.
Inbreeding means similar gene's in the two parent cells leading to an increased in recessive traits.
I'm not sure if I made my point clear... but hope this helps

Best answer choice is 2. Inbreeding does not increase mutations It does however increase your chance of receiving resessive allele that may contain a mutant trait.
