A scientist named Thomas Hunt Morgan studied genetics in fruit flies. Specifically he looked at wild type (normal) wings versus vestigial (shortened) wings. When he crossed a wild type female with a vestigial male he expected to see 50% parental phenotypes and 50% recombinant phenotypes in the offspring. However, what he actually found was 83% parental phenotypes and 17% recombinant phenotypes. What does this suggest about the genes he was studying? How do the percentages help us determine this?

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
