A man has a straight hairline. Is it necessary for both his parents to also have straight hairlines in order for him to have one? Use a Punnett square to explain your answer. Refer to Lab Videos for example.
Do you think albinism is caused by a dominant or recessive allele?
Albinism is a recessive trait that results in lack of melanin in the body. What is the probability that the offspring will have albinism if the parents are both heterozygous for the trait? I know the answer is 1/4 but dont know why.

- Two albino poodles met at a dog park and fell in love. The two dogs decided to be exclusive and not see any other dogs. One day the female poodle became pregnant; shortly after six beautiful puppies were born. However, much to the shock of the towns folks, they were all dark brown! Not that it's anyone else's business, for goodness sake, but did a handsome brown poodle catch the eye of our lady here? Or did she stay true to her one love? O She had to have an affair! It would be impossible for two albino dogs to have dark brown puppies, since albinism is a recessive trait. O It is possible for to two albino dogs to have non-albino offspring as long as there is more than one gene required for pigmentation.arrow_forwardWhy do close-relative marriages are now discouraged?arrow_forwardLooking at hairline (widow's peak = H) and ear shape (ear lobes = E)...

He checked in with a physician at the health center. She told him, “It’s probably just a large mole, but we should do a biopsy to find out for sure.” What genetic differences would you expect the pathology lab to find between a malignant tumor and an ordinary mole?arrow_forwardA girl is taking a genetics course on the ABO blood types where she learns that she has an O blood type.
