Answer:
mutations in proto-oncogene are generally cancerous while mutation in tumor-suppressor alleles are recessive and result lost of function
Answer:
Which type(s) of cell division reduce(s) the chromosome number by half?
Meiosis l
Which type(s) of cell division can be classified as reductional?
Meiosis I
Which type(s) of cell division can be classified as equational?
Mitosis and Meiosis II
Explanation:
Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.
Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.
