Is a progeny cell an haploid?
Hi
Something that has been nagging at the back of my mind. I am studying towards a life sciences degree with the OU. And I am currently studying cell division through mitosis and meiosis.
Now I have learned that through meiosis progeny cells are ensured to contain exactly half of the chromosomes of the parent cell. Being one of each pair of the autosomes and one of the sex chromosomes (in humans being 22 and 1 respectively).
My question is:
Am I right in thinking that through meiosis, that the above makes a progeny cell an haploid?
Just something that makes sense to me but I have never read of it anywhere
Many thanks

Re: Is a progeny cell an haploid?
HI! In meiosis the number of chromosomes is reduced on 1 half. When egg and spermatozoid fuse together you get "{normal" number of chromosomes in somatic cell.What's specific for meiosis is crossing over-the hromosomes exchange "parts", so you have a new combinations of genes.I have pictures but I can't paste them here.

Yes, you would be right about that. It is always haploid. At some algae the whole plant is haploid and the progeny cell is formed through mithosis. But it is ALWAYS haploid
