Last Answer : answer:
Description : Which of the following plant hormones are incorrectly paired? (1) abscisic acid- transpiration (2) auxins- apical dominance (3) cytoldnins- senescence (4) gibberlins- bud and seed dormancy
Last Answer : (4) gibberlins- bud and seed dormancy Explanation: Abscisic acid is responsible for responsible for dormancy of various types. It maintains dormancy in seeds and buds, stimulates the closing of stomata. Gibberellins are responsible for cell division and growth in cell size.

Last Answer : (b) Flowering
Description : Which of the following plant hormones are incorrectly paired? (1) abscisic acid- transpiration (2) auxins-apical dominance (3) cytokinins- senescence (4) gibberlins- bud and seed dormancy

Description : What happens when a red flowered plant with incomplete dominance is crossed with a pink flowered plant which is the offspring of the crossing of a white flowered plant and a red flowered plant which has incomplete dominance?
Last Answer : The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. ... ... the heterozygous offspring will be phenotypically and genotypically different from either of the homozygous parent.
