Answer 5

Answer 6

hello?

Answer 7

1. Dominant is normal and way say about atleast ½ of the next generation will inherate the gene. When recessive is traced it is usual that it sometimes overlap a generation, this can't be done for dominant. x-linked recessive would only follow the girls due to the fact it is recessive and you need xx to become a girl.

2. make a qualifyed guess and then try do a crosschat to see if it can happens... remember that one is sick/something else (black) and the white is normal.

3. again make a qualifyed guess and then try do a crosschat.

4. crosschart base your answer on question 1.

5. crosschart again to find out.

Answer 8

for 2=5 how do i do that?

Answer 9

Okay wanna do them 1 at the time together then?

Answer 10

sure :)

Answer 11

good good :)
2.
We need to find the genotype for nr. 1, we notice he have the condition, and we guess that the condition is dominat from question 1 agree?

Answer 12

yes

Answer 13

perfect, he is going to have the condition he can either have NN or Nn (N dominant).
Which one do you think it is and why?

Answer 14

Nn

Answer 15

That is right, becuase we notice that he have some children that don't have the condition and we can check the genotype Nn with a crosschart:
