Answer:
b.Allele of a gene separate from each other when homologs separate in meiosis I or in meiosis II if there is a single crossover between the gene and the centromere
Explanation:
The behavior of homologous chromosomes at late prophase 1 and metaphase1 and independent assortment at metaphase ii, with eventual separation (segregation to different sex cells showed the behavior of chromosomes as stated by the Mendel segregation laws.
D. the statement
---------------
I'm guessing here but, some advantages are, embryonic stem cells are very effective at repairing damaged tissues, but they are difficult to obtain, and either have to be obtained from umbillical chords of babies, or from fertilized embryos from a laboratory. So I am guessing they would be expensive/difficult to source because you would either have to collect umbillical chords from babies, or have to purchase eggs from women, and they are ethically questionable to use because you are essentially making potentially viable embryos and then killing them. Hope this helps.
