Homework Answers
Answer: Widow peak is dominant inheritance. So it is expressed in both dominant homozygous and heterozygous conditions. So it is clear that widow peaked individual may have either Homozygous widow peak (WW) or heterozygous widow peak (Ww).
Two Possible chances are
1) Parents possessing homozygous alleles of Widows peak individual and homozygous smooth hairline individual.

Genetics problem: (please show work or explain) You have freckles, dimples and a widows peak. Your significant other has freckles and dimples but has a continuous hairline. Freckles are dominant to no freckles Dimples are dominant to no dimples. Widows peak is dominant to continuous hairline. What are all of your possible genotypes? What are all of the possible genotypes of your significant other? How can you tell? Assuming that you are heterozygous for all three traits and your...

How can I solve genetic problems without using punnet square? how can i know the ratio espically in trihybrid cross? for example can someone solve it and elaborate ? In humans, "unattached" earlobes are dominant over "attached" earlobes. "Widows peak" hairline is dominant over "non-widows peak" hairline. Use E and e for the earlobe phenotype alleles, and W and w for the hairline phenotype alleles. A female and a male, both with unattached earlobes, have a child with attached earlobes....

Red-green color blindness is due to an X-linked recessive allele in humans. A widow�s peak (a hairline that comes to a peak in the middle of the forehead) is due to an autosomal dominant allele. Consider the following family history: A man with a widow�s peak and normal color vision marries a color-blind woman with a straight hairline. The man�s father had a straight hairline, as did both of the woman�s parents. Use the family history to make predictions about...
