It says she and him had one. Says it on second to last line of paragraph. If you do a proportion of 1/3 and X/12 you will get 4/12 so 4 of her 12 kids. I know i didnt explain it well but I am almost sure its right

8. man i said 4, before u lol. but i never hit post reply i went back up and read the second question.

9. So was I right?

10. All I can say is.....W...T.....F...

11. u first hate punnett sqaures and later then become second nature like 2^3=8

just wait till u get hybrid's

12. I got the answer 3 for the first part.

If T = Tongue rolling
and P = PTC test positive

Mother = TTpp (homo dominant tongue and homo recessive PTC)
Father = TtPp (Hetero tongue and hetero PTC)
The reason you know the father is hetero for PTC is because he has a child who is pp so the father cannot be homo dominant for PTC.

If you put this into a Punnet square you get this:

```|  TP     |   Tp    |    tP    |    tp    |
Tp| TTPp  |  TTpp  | TtPp   |  Ttpp   |```

25% are TTPp
25% are TTpp
25% are TtPp
25% are Ttpp

The question asks how many are homo dominant for tongue rolling and homo recessive for PTC test. That is TTpp.
25% of 12 is 3.

PWNED

13. meh..
