Which statement about tRNA is not correct?

Bringing up an old questions on answering techniques for inheritance patterns 1) Prove whether it’s dominant or recessive FIRST 💡 - 2 affected parents -> 1 unaffected = dominant - 2 unaffected parents -> 1 affected = recessive 2) Prove whether it’s autosomal or sex linked! Some tips - See if there are disproportionally more male/ female affected - if determined to be dominant from part 1, a pro tip to check if sex linked -> all affected fathers will have affected daughter (if this holds true it’s sex linked if not it’s autosomal So for this diagram the ANSWER - generation III both affected parents give rise to unaffected offspring = dominant - affected father in generation III but there is unaffected daughter = autosomal
