5 True/False questions
maternal inheritance → A type of uniparental inheritance in which all progeny have the genotype and phenotype of the parent acting as the female.
gene: → The entire complement of genetic material in a chromosome set.
Southern blot → The transfer of electrophoretically separated fragments of DNA from a gel to an absorbent sheet such as paper; this sheet is then immersed in a solution containing a labeled probe that will bind to a fragment of interest.
telomere → A cell in which meiosis takes place.
diploid: → A pair of sister chromatids joined at the centromere, as in the first division of meiosis.
