The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
I'm thinking either the first or second answer. Sorry if this doesn't help.<span />
Creating a genetic duplicate of an organism using biotechnological methods is known as reproductive cloning.
<h3>Reproductive cloning</h3>
Cloning generally refers to the production of clones.
Clones are exact copies of an organism or something.
When it comes to living organisms, clones are both genetically and physically the same.
Thus, creating a genetic duplicate of an organism is a form of cloning known as reproductive cloning.
