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.
