The right answer is A) Trisomy
Aberrant karyotypes containing an abnormal number of chromosomes are known in the human species. The best-known (and most common) chromosomal abnormality is trisomy 21, which is responsible for Down syndrome (mongolism). There are others such as Turner syndrome (woman with a single X chromosome) or Klinefelter syndrome (man XXY).
These abnormalities originate from the non-disjunction of the chromosomes of a pair of homologues during metaphase I of meiosis. At the end of division I, a daughter cell contains the two chromosomes of the pair considered and the other cell does not contain a chromosome of this pair. A similar result can be obtained during a bad distribution of chromatids during anaphase II.
After fertilization from a gamete of this type, a trisomy or a monosomy is obtained.
The correct answer is angiosperms.
The angiosperms, also known as the flowering plants, they are the most varied group of land plants with more than 400 families, and about 13000 known genera.
Similarly to gymnosperms, the angiosperms are seed-bearing plants. However, they are separated from gymnosperms by the features like endosperm within the seeds, flowers, and the generation of fruits, which comprise the seeds.
