Assertion : When yelow bodied, white eyed Drosophila females were hybridised with brown-bodied, red eyeed males , and F_(1) progeny was intercrossed, F_(2) ratio deviated from 9:3:3:1 Reason : When two genes in a dihybrid are on same chromosome, the proportion of parental gene combinations are much higher than the non-parental type

With regards to toxicity and the need for dilution in water, how different are ureotelic and uricotelic excretions? Give examples of animals that use these types of excretion. Ureotelism: 1. The process of excreting urea is called ureotelism. 2.Animals which are found in places where water availability is not abundant have this mode of excretion. 3. They convert Ammonia produced in the body into urea in the liver and release it to the blood. This is filtered and excreted by the kidneys, Eg: Mammals, many terrestrial amphibians and marine fishes. 4.In terms of toxicity urea is more toxic than uric acid but it is soluble in water and is thus excreted as urine.
