What is an alllele? biology

An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Hope this helped!!  :)

a given gene, meaning it is one of two or more versions of a known mutation at the same place on a chromosome. It can also refer to different sequence variations for a several-hundred base-pair or more region of the genome that codes for a protein.

Explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
