Two parents decide to have a child. The parents plan to have their genes tested before they have their child to see if there is a possibility of their child having sickle cell, a recessive blood disorder. The parents find out they are both heterozygous. What percentage does their child have to get sickle cell?

1/4 chance.

Explanation:

I used a punnet square to calculate the possibility and it seems to be a one in four chance.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
