How many chromosomes are in a tetrad
WebMar 13, 2024 · The tetrad which is developed during the zygotene stage consists of four homologous chromosomes with four chromatids. Thus the correct answer is Four … 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”.
