In a tissue-culture lab, a scientist prepared somatic embryos of a banana. he wants to induce root development. which hormone type should he apply to achieve this?
a) cytokinins
b) gibberellins
c) ethylene

A) cytokinins

Explanation:

Cytokinins are the class of plant growth regulating hormones. Their function in plants is to promote the cell division and differentiation in plant shoots and roots. Therefore, they help in the elongation process of the plant from both ends roots as well as shoot. They cause the expansion of the cells of plants.

On the basis of the above description, cytokinins can be used to induce root development in the tissue culture.

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
