Answer:
In humans, both sperms and ova contain 23 chromosomes.
Explanation:
During fertilization, the diploid chromosome number 46 is regenerated in the zygote. After 24 hours of fusion, human zygote starts to divide by mitosis, commencing the embryonic period. The zygote is divided into 2-cells, 4-cells, 8- cells and then 16-cells
C. Energy that is the correct answer
Answer:
1. 20 chromosomes
2. 10 chromosomes
3. 10 chromosomes
Explanation:
1. The process of mitosis results in the two daughter cells from the same parental cell with exactly the same genetic material. Thus the two cells contain the same number of chromosomes as the parent cell. Therefore if a cell with 20 chromosomes undergoes mitosis will result in the 20 chromosomes.
2. During meiosis I two daughter cells are formed with different ploidy levels as the number of the chromosome reduces to half. Therefore the cell with 20 chromosomes results in two cells with 10 chromosomes.
3. During meiosis II, the two daughter cells formed from meiosis I result in the formation of two more daughter cells with an exact number of chromosome number that is 10 chromosomes.
