Suppose that tail length in horses is controlled by a number of additive genes, each of which has 2 alleles. when a true-breeding female with a 12-inch tail is mated to a true-breeding male with a 36-inch tail, all f1 offspring have the same tail length. when the f1 offspring are mated to each other, 7 different tail lengths are seen in the f2 offspring. how many genes contribute to tail length?

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.

explanation:

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.
