Georgia [21]

Answer:

llbb

Explanation:

<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>

Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.

<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>

Hitman42 [59]

Coelophysis was one of the first true dinosaurs to appear in the late Triassic, is was an agile, bipedal carnivore.

Coelophysis was a small fast running carnivorous dinosaur. Coelophysis was found in Upper Triassic. Coelophysis means 'hollow form', and this comes from the hollow limb bones. Coelophysis was a light-weight hunter that looked like a bird having long legs. The Fossil evidence shows that this dinosaur ate small crocodile-like reptiles. This predator was about 9 feet long.
