A cross between Ttrr and TtRR snapdragon plants where T is the dominant allele for plant height (tall), t is the recessive allele for plant height (dwarf), R is the dominant allele for flower color (red), and r is the recessive allele for flower color (white) would result in what proportion of offspring with pink flowers on dwarf plants

The traits are the result of genes that have a physical association on the same chromosome.

Explanation:

The ability to control mating between pea plants

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
