Widow’s Peak (point in hairline) is dominant to a straight hair line. Complete a punnett square using two parents who heterozygous for having a widow’s peak (Ww). What is the percent chance that the offspring will have a straight hair line?

It's a 1/4 chance. Because there is a 1/2 chance that each parent will put fourth the recessive gene and 1/2x1/2 is 1/4!!!!!

25 %. You will have WW, Ww, Ww and ww when you do out the punnetts square. The "ww" is the double recessive for straight hairlines.

from what i remember, if there are two dominant genes involved then there is no chance of inheriting a straight line...you will only get a recessive, like blue eyes, if neither parent has a dominant gene...in order to get a recessive both parents must have the recessive gene, only one dominant gene is needed to produce a dominant gene...i could be wrong though
