Nondisjunction is defined as the failure of the chromosomes to seperate during cell division. An animal with a haploid number of 6 (diploid number of 12) undergoes meiosis, and at the meiosis II (cells are already haploid from the meiosis I), nondisjunction occurs. The mature ovum will contain 6+1 chromosomes (n+1) because there is an extra chromosome from the nondisjunction. The second polar body will contain 5 chromosomes (normal would be 6) because the second polar body did not receive that extra chromosome due to nondisjunction. In the event of fertilization of the abnormal ovum with a normal sperm, the zygote will be a diploid (12 chromosomes) normally but since the ovum as an extra chromosome from the nondisjunction then the zygote will have an extra chromosome (13 chromosomes). One pair of chromosomes has an extra single chromosome and this is called a trisomy.
Answer:
males have one x and one y chromosome tho if its one choice its most likely y
Explanation:
Answer: d. cerebrum
Explanation:
The cerebrum is the uppermost and largest portion of the brain. It consists of two cerebral hemispheres, which accounts for the two-thirds of the total weight of the brain. The left hemisphere has function in controlling the language and speech. The other one interprets the spatial and visual information from the stimuli. The cerebrum is also the thinking part of the brain it also controls the movement of the voluntary muscles.
