5 Multiple choice questions

5 True/False questions
X linkage → The inheritance pattern of genes found on the X chromosome but not on the Y chromosome.
meiosis → A type of nuclear division (occurring at cell division) that produces two daughter nuclei identical with the parent nucleus.
quantitative trait locus (QTL) → A gene contributing to the phenotypic variation in a trait that show complex inheritance, such as height and weight.
propositus → Two successive nuclear divisions (with corresponding cell divisions) that produce gametes (in animals) or sexual spores (in plants and fungi) that have one-half of the genetic material of the original cell.
histone → A type of basic protein that forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes.
