Consider the following scenario: There are two products X and Y that are being manufactured. As a part of the process, both X and Y need to be processed on a machine which has 100 hours available. Each product X and Y needs 2 hours for each unit. Which of […]

A skin cell from a human female undergoes mitosis. For an unknown reason, the centromere of one of the two number 4 chromosomes fails to divide. Describe the resultant chromosome number of the two daughter cells. Indicate the genetic make-up each cell. Suppose this happened to a single cell in […]
