34 What happens during meiosis? D A A haploid cell produces haploid cells that are genetically identical. B A haploid cell produces haploid cells that are genetically different. C A diploid cell produces haploid cells that are genetically identical. D A diploid cell produces haploid cells that ar...
During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another. What happens when meiosis has a glitch? The phenomenon of unequal separation in meiosis is called ...
mitosis is more common. In fact, whereas only sexually reproducing eukaryotes can engage in meiosis, all eukaryotes — regardless of size or number of cells — can engage in mitosis. But how does this process proceed, and what sorts of cells does it produce?
What is Diakinesis in meiosis? Diakinesis isthe last stage of meiosis prophase-1(a five-stage process). Diakinesis stage is characterized by chiasmata terminalization. After diakinesis, the dividing cell enters metaphase. At this stage, bivalents distribute them evenly in the nucleus. The nucl...
However, in order to understand what happens at the chromosomal level, the whole cell is considered carefully. In the last chapter we stated that the processes of genetic recombination in meiosis are: (1) crossing over of chromatid segments during prophase I and (2) random distribution of ...
During meiosis, the homologous chromosomes line up with each other so that they can be separated into different sex cells.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer See full answer below....
"Meiosis generates new genetic combinations, andnatural selectionacts on that. Everything we see in evolution is a product of what happens in meiosis," Bhalla said. The chromosomal monitoring system she studies involves a series of checkpoints to ensure that each step in meiosis is completed prop...
Synapsis is the pairing of homologous chromosomes during prophase I of meiosis I. During interphase, DNA is duplicated, and in a diploid organism the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
Genes are inherited from parents and, once their specific sequence after recombination during meiosis is established, they remain almost unaltered through cell divisions during an individual’s life, unless external agents or replication mistakes act on them producing mutations. However, changes in epigen...
