Answer:
The result will be two gametes with a normal haploid number (n), one gamete containing an extra chromosome (n + 1) and one gamete missing one chromosome (n − 1).
Explanation:
Nondisjunction is caused by the failure in the mechanism of separation of homologous chromosomes or sister chromatids during meiosis and/or mitosis. The failure in the separation of sister chromatids during meiosis II is referred to as 'secondary nondisjunction' and it produces two daughter cells with abnormal chromosome numbers.
The fusion of one gamete containing an extra chromosome (n + 1) with a normal (n) gamete will lead to trisomy (2n + 1), while the fusion of one gamete missing one chromosome (n - 1) with a normal gamete will lead to monosomy (2n-1).
Answer
Hi,
An object with the largest size will have a large gravitational force acting on it. Explanation
The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.
Best wishes!
Answer:
1/(5⁹) or 5⁻⁹
Explanation:
This is a Mathematics question rather than a Biology question.
The given fraction is:
This fraction can be rewritten as:
Therefore, the quotient of the given fraction is 1/(5⁹) or 5⁻⁹
