Crossing over<span> occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.</span>

ycow [4]

Answer:

During <u><em>vegetative propagation</em></u>, a new plant grows from parts of the parent plant.

During<u><em> mitosis</em></u> , a new plant grows from parts of the parent plant.

Explanation:

<em>Asexual reproduction can be described as a type of reproduction in which only one parent is involved and the daughter cells formed are identical to the parent cell.</em>

In vegetative propagation, a vegetative part of the plant such as roots, shoots etc are taken and grown separately. A new plant arises from these parts of the plant.

Mitosis is a type of asexual reproduction in which only a single cell undergoes division to produce two new daughter cells which have the same genetic makeup as the parent cell.
