Explanation:
The two categories of the behavior includes the operant behavior and respondent behavior.
Operant behavior: The operant behavior can be define as the behavior that is under the control of the consequences. These consequences are likely to control the future frequency of behavior. For example, A child who is allowed to hit other children and take their toy, is likely to be aggressive to other people in the future.
Respondent Behavior: The behavior which is under the influence of a specific stimuli is a respondent behavior. For example, Snapping of hand away from a hot pan, and Salivation of the mouth due to food.
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.
