Now, suppose that the three tomato genes from part a did not assort independently, but instead were linked to one another on the same chromosome. would you expect the phenotypic ratio in the offspring to change? if so, how? which statement best predicts the results of the cross mmddpp x mmddpp assuming that all three genes are linked?

All eight phenotypes are possible but parental phenotypes will be more in number

Explanation:

In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:

In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.

If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.

cancer   is   essentially   uncontrolled   mitosis   of specialized cells

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.
