A. 15
B. 30
C. 45
D. 60
E. 120
17. A diploid cell has 42 chromosomes. How many chromosomes are present in each cell during
metaphase II of the meiotic cycle?
A. 168
B. 84
C. 63
D. 42
E. 21

Answer 1

Answer:
16. B
17. E
Step-by-step explanation:
16. During prophase I of meiosis only crossing-over occurs. The cells do not halve.
17. The cells split into 2 at the end of telophase I. They'll only split into four at the end of telophase II so during metaphase II there will be only two cells each containing of 21 chromosomes.
