Final answer:
The statement about aneuploidy in human embryos being low is False. Aneuploidy including both monosomy and trisomy is relatively common, with some conditions like Down Syndrome allowing for survival post-birth.
Step-by-step explanation:
The statement that aneuploidy in human embryos is quite low is False. Aneuploidy refers to the presence of an abnormal number of chromosomes in a cell. In humans, the correct number of chromosomes, termed euploidy, is 22 pairs of autosomes and one pair of sex chromosomes. Cases of aneuploid, which include monosomy (loss of a chromosome) and trisomy (gain of an extraneous chromosome), are fairly common.
Most embryos with monosomy do not develop to birth due to missing essential genes. On the other hand, some embryos with autosomal trisomies may survive, depending on the chromosome affected. For example, trisomy of chromosome 21 leads to Down Syndrome, a condition where individuals can have a range of developmental challenges but can survive post-birth.
