Solution:Concept: The entire number of genetic traits that make up a species' genetic composition, which differ greatly from species to species and may be correlated with the species' survival time, is known as genetic variance.
Genetic variety in a species' genetic makeup refers to all genetic traits present in that species. It differs from genetic variability, which is the tendency for genetic traits to vary.
Crop diversity refers to the variation in the genetic and phenotypic traits of agriculturally important plants. Crops might differ in terms of fruiting time, flavour, blossom colour, height, branching style, and seed size.
Hence, the correct answer is option 1.
