WebOct 28, 2024 · How many chromatids are present in a tetrad? During prophase I and metaphase I of meiosis, a chromosome consists of a tetrad (4 chromatids or 4 DNA molecules) and is reduced to two chromatids (2 DNA molecules) by the time metaphase II occurs. Are there 4 chromatids in a chromosome? WebSep 4, 2024 · At the end of prophase I, the pairs are held together only at the chiasmata; they are called tetrads because the four sister chromatids of each pair of homologous chromosomes are now visible.

WebTelomeres are the caps at the end of each strand of DNA that protect our chromosomes, like the plastic tips at the end of shoelaces. So, in maize, the number of bivalent and tetrad is 20, Each chromatid has 1 DNA so in 40 chromatids DNA is 20*2=40, Each DNA has 2 telomers so Telomeres is 40*2=80 Correct answer is “20,20,40,80”. csu long beach emergency managementWebWe can see that there are 19 pairs of chromosomes which means there are 38 chromosomes totally present in this karyotype.
