Colorblindness is a sex-linked recessive trait. if b=normal and b=colorblind, what would be the genotype of a normal male? question 1 options: xby xbyb xbxb xby

The Genotype of a normal male wil be: XBY.

Explanation:

A sex linked recessive disorder is expressed only in males because males have only one X chromosome and so only one allele for this gene can be present in them.Hence, if the recessive allele is present then colour blindness will occur.If the dominant allele is present then the male will be normal.XbY has a recessive allele so the male with this genotype will be color blind.XBYb cannot be aoption because Y chromosome cannot have the allele of the gene.XBXb is a female carrier's genotype.XBY has the dominant allele and so the man with this genotype will be normal.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
