What does human gene pool mean? What does no gene flow mean? What does autosomal DNA mean? In an alternation of generations life cycle, what alternates? What does deme mean in biology (genes/mating)? What is meant by biodiversity in the gene pool?
What is the meaning of the term biology? What is the definition of the term biology? What is environmental microbiology? (Please define in your own words.) What is the best definition of biology? What does biology mean? Explain what is meant by the word centriole as used in biol...
Meiosis is atype of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two co...
:the act or action of propagating: such as. a : increase (as of a kind of organism) in numbers. b : the spreading of something (such as a belief) abroad or into new regions. c : enlargement or extension (as of a crack) in a solid body. What does propagation mean in plants? Pl...
Nondisjunction may occur whenever a cell divides its chromosomes. This happens during normal cell division (mitosis) and gamete production (meiosis). Mitosis DNA replicates prior to cell division. The chromosomes line up in the middle plane of the cell during metaphase and the kinetochores of sister...
My hubby & I tried for pregnancy for roughly 7 years with no luck…. I’ve had 2 surgeries, 7 IUI cycles, and 1 failed IVF cycle using my own eggs, in addition to countless tests, procedures, etc. Although it was a extremely difficult decision to make, we finally decided to use don...
and survived for a matter of months. On a smaller scale, this sort of chromosomal mutation is more commonly seen in certain cell types of the body, such as in the heart or liver. Tetraploidy can also occur, with an even lower survival rate, as this would mean having 92 chromosomes (...
does not have an existence independent of such biases, and that it may in fact be misleading us into missing key aspects of the underlying biology that might indeed be understood free of such biases. In order to make that argument, we first need to establish what it would mean for aging ...
As mentioned in the last paragraph, the ability to control the outcome is far from perfect. Until it is possible to manipulate the process so that a specific desired outcome can be produced with regularity, it would appear science does still have a long way to go. ...
It recognizes the reproductive intent of those who, say, do not contribute a gamete to the process, or of a female who does not gestate the child she intends to rear. It also recognizes instances where an individual or couple intend to rear a child whom they neither beget nor bear, in...
