Answer: haploid, 23 chromosomes and 23 chromatids of
Explanation:
Meiosis takes place in two divisions meosis 1 and meosis 11.
Meiosis 1 is reduction division, because two new daughter nuclei are formed with haploid chromosomes number of the parent nucleus.
Therefore based on this question; the 46(2n) chromosomes in example the ovary will be halved to (23)n. 2n ⇒ n .
So far chromatids, are newly formed chromosomes there will be 23 chromatids, since the haploid chromosomes are 23 in number
However, so far the entire new daughter cells contains half the total chromosome number of the parents they are haploid.
