**This question was stated in Bootcamp, but I perform not really know the principle of it. "If 2n=46, how numerous tetrads are existing during metaphase 1? The answer to be 23..Can friend guys explain the concept behind this?**

Tetrad = 2 homologous chromosomes (aka 4 chromatids) room paired and appear together one structure in Metaphase of Meiosis I. Humans have actually 46 chromosomes, however if friend pair the homologs together you will have 23 tetrads.

The 2n to represent diploid. A tetrad is a mix of 2 chromosomes, therefore that would divide the diploid number in fifty percent (still diploid yet that"s no what it"s asking for).

You have to think of it this way, during Meiosis I, particularly Prophase I. The chromosomes type tetrads the nonsister chromatids. Tetrads are just two chromosomes paired up together. So that is asking throughout Metaphase I, i beg your pardon is once independent assortment will eventually happens, however not yet. For this reason the tetrads room lined in the middle throughout metaphase I. Think that it like this. How numerous pairs have the right to you make v 46 chromosomes? just 23.

I think everyone described it yes, really well. Tetra (numerical prefix for 4) refers to the quantity of chromatids per tetrad. and also a diploid cell ( 2n=46 ) has actually 92 chromatids, therefore 92 divided by 4 is 23 tetrads.

thanks everyone! perform you males know exactly how to solve the difficulties where the asks how numerous chromosomes space in anaphase? in Meiosis II Anaphase? etc..Those kind of questions? i am kind of battle with that together well..

The easiest method is to counting the variety of centromeres in each phase the it asks about. Every centromere counts together a chromosome. more detailed explanation: In mitosis, a 2n=46 cell would have 46 chromosomes and 92 chromatids. as soon as the chromosome separates, notification that the number of centromeres has doubled since each chromatid now has a centromere. In anaphase, every chromosome separates into two chromatids. As soon as a chromatid is by itself, the is now dubbed a chromosome by definition. The 92 chromatids space all separated in anaphase and also are all labeled as chromosomes. (Total of 92 chromosomes in anaphase) In meiosis Anaphase II, that is analogous come the Anaphase in mitosis, except that the chromosome number had been lessened from Telophase I. (46 come 23 chromosomes) Therefore, 23 chromosomes are separated right into 46 separation, personal, instance chromatids. Remember that each chromatid now has a centromere and also is labeled together a chromosome. (46 chromosomes in Anaphase II of meiosis) allow me know if friend need assist with anything rather
