How many haploid cells are produced during meiosis I? a) 1 b) 2 c) 3 d) 4 How many chromosomes does each daughter cell contain? Somatic cells of the fruit fly have 8 chromosomes. How many sex chromosomes are in a somatic cell?

Megasporogenesis. In gymnosperms and flowering plants, the megaspore isproduced inside the nucellus of the ovule. During megasporogenesis, a diploid precursor cell, the megasporocyte or megaspore mother cell, undergoes meiosis to produce initially four haploid cells (the megaspores). Do megaspores...
The effects of ATZ on reproduction have been extensively studied; however, the effect of ATZ on meiosis has not been elucidated. Meiosis is the division of germ cells and is essential for the production of haploid gametes. In most organisms, homologous recombination (HR) is important for the ...

The mitosis-to-meiosis switch during spermatogenesis requires dynamic changes in gene expression. However, the regulation of meiotic transcriptional and post-transcriptional machinery during this transition remains elusive. We report that methyltransfera
After a primary oocyte divides meiotically,three haploid cellsare produced. At what stage of meiosis do developing ova become Meiotically arrested? At around 20 weeks' gestation, oogonia become primary oocytes, and their development is arrested inprophase Iof meiosis. The oocytes' development remains...
One primary spermatocyte produces four round haploid spermatids after two successive meiotic events [3]. Although gene expression in germ cells at different stages is strictly regulated at the transcriptional and post-translational levels, the detailed mechanisms remain unclear. N6-methyladenosine (m6A)...
