ok more bio questions?

1.) heterozygous
2.)0 percent
3.) 1 homozygouz dominat
1 homozygous recessive
and 2 heterozygous
4.) idk
5.)if is shaded or not...shaded is dominat not shaded would be recessive...

I THINK my answers are right, but i would double check, i love doing this stuff =]

1.  heterozygous
2.  0    RR x RR all RR
3.  1/2 or 50%    Rr x Rr RR, Rr, rR, rr
4.  Studying a pedigree is like following a treasure map.  You have to start with what you know for sure and trace the traits through the generations.  If a trait is sex-linked and recessive, any daughters with the trait must have fathers with the trait.  Start suspecting sex-linked traits if the trait shows up almost entirely in males.  If neither parent has the trait but the daughter does have the trait, that means the parents were both carriers and the trait must be autosomal.  No males can be carriers of X-linked traits.

5.  Again, look around at the pattern of traits in the generations on the pedigree.  If any offspring has the trait and has two parents without the trait, then the trait must be recessive.  If two parents have the trait and have any offspring without the trait, then the trait must be dominant.

1) heterozygous
2) 0%
3) 50%
4) Whether the trait most commonly shows up in males. If so, the trait is sex linked. Men have only one X chromosome so they do not have another "good" chromosome to mask the trait as do females. Females must be homozygous for the trait in order to display it, while males are hemizygous for it, they only have one allele.
5) They study the offspring of people carrying the trait that mate with others that also carry it. If some of their children do not carry the trait, then it is definitely recessive. If parents that do not display the trait produce offspring that do, it is recessive.

4.  Sex linked:

-usually passed from mothers to sons or fathers to daughter
-usually skip generations
-i dont remember and don't have my notes handy haha
