Assume that short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you find a black, short-haired animal, you can determine its genotype by crossing it to an animal with a genotype of

You can determine its genotype by crossing it to an animal with a recessive genotype, llbb.

Explanation:

A test cross is performed when there is an individual with an unknown genotype and we desire to know if it is a heterozygote individual or a dominant homozygote individual.

The cross occurs between the individual of unkown genotype and a recessive homozygote individual.

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).
