Document Summary
The generation-to-generation sequence of stages in the reproductive history of an organism, from conception to production of its own offspring. Sets of chromosomes in human cells: each somatic cell has 46 chromosomes, there are two chromosomes of each of 23 types. A display of the chromosome pairs of a cell arranged by size and shape. Two chromosomes of a pair that have the same length, centromere position, and staining pattern. Chromosomes that are not directly involved in determining sex; not a sex chromosome: we inherit one chromosome from each of our parents. 23 chromosomes paternal set: the number of chromosomes in a single set is represented by n. Has a diploid number of chromosomes = 2n. 2n = 46: in a cell in which dna synthesis has occurred, all the chromosomes are duplicated, and each consist of two identical sister chromatids, associated closely at the centromere and along the arms. How many sets of chromosomes are present in fig.
