Answer:

A) In this wild mustard, there is enough heritable variation to permit these different varieties.

Explanation:

Brussels sprouts, broccoli, kale, and cabbage were developed by breeders by the process of artificial selection of one or other genetic traits. The processes of natural and artificial selection require the presence of genetic variations in the population to act upon. <em>Brassica oleracea </em>had the variations such as overlapping leaves (for cabbage), storage stem (for kohlrabi), large axillary buds (for Brussels), etc. These strains of <em>Brassica</em> with desired genetic traits were selected and bred for several generations to produce the above-mentioned strains.

1. Classification means the grouping of organisms on the basis of
Vlad1618 [11]

Answer: b) common features.

Explanation: Classification is the way we decide on relationships between groups of organisms, and this is done in several levels in a hierarchy. For example, all plants form a group based on having chlorophyll and being photosynthetic (the plant kingdom), which other kingdoms like animals and fungi do not. Within plants there are divisions, like angiosperms - plants with flowers. The closest relationships are between species in the same genus, plants that have the same kind of flowers and seed, like the Flanders poppy and California poppy.
