Final answer:
The mutation in Mirabilis jalapa is a translocation, a type of chromosomal mutation where a segment of one chromosome attaches to a different chromosome.
Step-by-step explanation:
The mutation in Mirabilis jalapa is caused by a chromosomal mutation known as translocation. This type of mutation occurs when a segment from one chromosome breaks off and attaches to a different chromosome. Chromosomal manifestations like translocation, deletion, and duplication can lead to various abnormalities, depending on the positions of the affected genes.Examples of chromosomal mutations include a deletion, where a large section of a chromosome is lost, and a duplication, where a section of a chromosome is repeated. An inversion occurs when a piece of a chromosome breaks off, flips around, and rejoins. Each of these can have different consequences, such as physical and mental abnormalities, genetic imbalance lethal to a diploid organism, or the creation of aneuploid gametes.
