Answer:
The result of non-disjunction of chromosomes during meiosis, producing three copies of the chromosome in the embryos -instead of two- is called trisomy.
Explanation:
With reference to genetics, a cell is diploid because it has an even number of chromosomes, distributed in pairs - each of which is contributed by a parent - and responds to the formula 2n.
In trisomy, non-disjunction during meiosis of the homologous chromosomes causes an overloadin the corresponding gamete, which during fertilization will originate an embryo whose formula is 2n+1.
Trisomias are considered mutations, which can physically and functionally affect an individual, or even make an embryo not viable. <u>This defect can occur in both autosomes and sex chromosomes</u>.
A very common example of this mutation corresponds to the trisomy of chromosm 21, known as Down syndrome.
