Explanation:
Spliting the alleles and pairing them usng the two characters listed, The male pea plant will have four possible alleles: RS, Rs, rS, and rs. The female also we have the same. Using punnet's square, we are to cross the two parents, Using gentotypes obtained from this cross; RRSS, RRSs, RrSS, RrSs, RRSs, RRss, RrSs, Rrss, RrSS, RrSc, rrSS, rrSs, RrSs, Rrss, rrSs, rrss. The phenotupic ration will be 9 Round starchy: 3 Round waxy: 3 Wrinkled starchy: 1 wrinkled waxy. It cannot be said that none of the progeny will be wrinkled waxy.

Cons of HeLa cell:
- The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.
Explanation:
HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.
