i think he took a **** and came up with the answer or im i missin somethin

In the future it would be more beneficail to other SDNers if you would post the question. Anyway if there is a 1/50 chance to have the autosomal recessive gene then you do agree that the person has a 2% chance to get it, correct? Okay, now make a regular cross between a X1Y and a X1X. (the one signifies a carrier) The chances that a child will be diseased will be 25%, agree? Good but now since it was a 2% chance that Dad had it and 2% chance that Mom had it so we multiply 2% *2% * 25% and get .01%

Its math but I hope this helps you.

It doesnt say that they have it. It says they are 1/50 to have it Ten the question ready bare taht in mind now what would would happen if any random male and female mated- so first take into consideration if they have it in the first place and then if there kid will have it- better?

i had the same question. if it says that they are both carries then why do you need to incorporate the 1/50? does the question mean what is the probability that two people will have a diseased child? so then you would need to know the probability of two heterozygous people coming together to make a baby multiplied by the probability of their child being affected? did i interpret it correctly?

Humm I see what you people are saying- i am almost positive that there was a change in class and he switched it to what are the chances that a random male and female come together
I only realized that he corrected teh mistake in class now----
are we good now?

this question is wrong we disscused about that before. when question says the parents are carrier it doesn't make sense to consider 1/50 in our calculaton. if the question ask the random mating the answer will make sense.
