Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
Answer:
Yes.
Explanation:
Yes, to calculate percentage of cells in each phase, we will divide the total number of cells in each phase of mitosis or meiosis by the total number of cells, and then multiply by 100 to get the percentage of cells in each stage. In that way we can find out that how many cells present in which phase of the cell cycle. Most of the cells about 80 to 90 % of cells spent their time in interphase.
