Answer:
alleles ,genes

Mendel's law of independent assortment states that alleles randomly assort their genes during formation of haploid cells. The paired factors that determine an organism's characteristics segregate separately from each other during sex cell formation.
Environmental manipulation of a crop can not only have unexpected consequences, but also have a negative impact on the atmosphere as well. The crops produced might be of inferior quality than expected. The amount of crop that grows can also be less. More water might be needed for the crops to grow.
All of the above- 1, 2, and 3 These introduce variation into the chromosome or into the zygote and create cells and offspring unique from the parents.
