A geneticist studied the genome of a child. The geneticist discovered that the genetic material of the child had three copies of chromosome 13. How would the geneticist learn this type of information about the child’s genome?

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

the question isn't complete here so i can't right an answer '_'

i dont know it at allnow im just getting points at this pint

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
