I need help with exceptions to Mendel's rules!?

Question

1. What are 2 exceptions to mendel's rules?

2. What are six blood group genotypes/phenotypes?

3. Which 2 blood types are codominate?

4. What chromosone determines gender?

5. This is a stituation in which the arms of 2 chromosomes overlap and exchange genetic material

6. Red-green color blondness and hemophilia are non-lethal x-linked recessive dissorders. A man who isn't colorblond marries and has kids with a woman whos a caarier. Can they have colorblind kids?

7. If a male has a genetic x-linked disease did he get it form his mom or dad?

8. Can a male be a carrier for an x-linked genetic disorder?

ANYTHING YOU CAN ANSWER WOULD BE GREAT! THANKS

Answer 1

1. Linkage & incomplete dominance.

2.Genotypes: AA,AO,BB,BO,AB,OO

    Phenotypes: A,B,AB & O

3.Only AB is codominant.

4.s*x chromosomes; X or Y.

5.crossing over and translocation

6.Yes, 50% chance that a male child will be colorblind.

7.mom

8.No

Note: this is not a "botany" question.

Answer 2

4.23rd chromosomes determine gender

7.His mom, because fathers give the y chromosome to male children.

8.No he would be diseased not a carrier. Because to be a carrier you have to have at least one healthy x chromosome and males only have so if that one was compromised they are screwed.
