The crossing over of homologous chromosomes and the independent assortment of chromosomes occur only during meiosis. How do these two processes result in genetic variation of organi? o Gene combinations of daughter cells are different from the parent.
The daughter cells produced become reproductive cells
They occur in sexually reproducing organisms
The daughter cells are haploid

The mixture of sperm and fluids from the seminal vesicles, prostate gland, and cowper's glands is called

The process of meiosis produces only gametes, eggs or sperm. according to the diagram, how many sperm are formed from each cell that undergoes meiosis?

Assume that you are interested in separating short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range. you have two recipes for making your polyacrylamide gels: one recipe uses 1.5 percent agarose and would be considered a “hard gel,” while the other uses 0.5 percent agarose and would be considered a loose gel. which gel should you use to separate the short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range?
