Title: Unit 4 SAC 1
Post by: zool3 on July 22, 2011, 01:59:10 pm

First sac is next week, wondering if anyone has tips to analyse pedigrees quickly and easily? and also have external resources (questions) on pedigrees.

Thanks in advance!! :) :)

Does it skip a generation? If yes - recessive. If no, check more closely to determine dominance.
Are there equal numbers of men/women affected? If yes - autosomal (note this requires a reasonable sample size and you should still check the specific pattern)
