Test: Zoology Mock Test - 9 - Question 1

A gregarious but nonsocial animal is

Detailed Solution for Test: Zoology Mock Test - 9 - Question 1
Locust, (family Acrididae), any of a group of insects (order Orthoptera) that are distributed worldwide, the common name of which generally refers to the group of short-horned grasshoppers that often increase greatly in numbers and migrate long distances in destructive swarms. In Europe the term locust denotes large acridids, whereas smaller species are called grasshoppers.
A phase theory has been developed to account for the sporadic appearance and disappearance of locust swarms. According to the theory, a plague species has two phases: one solitary and the other gregarious. The phases can be distinguished by differences in coloration, form, physiology, and behaviour. A solitary-phase nymph, for example, adjusts its coloration to match that of its surroundings, does not collect in groups, has low metabolic and oxygen-intake rates, and is sluggish. A gregarious-phase nymph, on the other hand, has black and yellow or orange coloration in a fixed pattern, gathers in large groups, has high metabolic and oxygen intake rates, and is active and nervous. Adult locusts differ more in form than in colour. The solitary phase has shorter wings, longer legs, and a narrower pronotum, or dorsal sclerite (with higher crest and larger head), than the gregarious phase. The adult of the gregarious phase has a more saddle-shaped pronotum, broader shoulders, and longer wings.

Albinism is known to be due to an autosomal recessive mutation. The first child of couple with normal skin pigments was albino. What is the probability of their second child will also be an albino ?
Detailed Solution for Test: Zoology Mock Test - 9 - Question 18
Albinism is caused by the absence of the enzyme tyrosinase which is essential for the synthesis of the pigment from dihydroxyphenyalanine. The gene for albinism (a) does not produce the enzyme tyrosinase but its normal allele (A) does. Thus, only homozygous individual (aa) is affected by this disease. Albinos (individuals with albinism) lack dark pigment melanin in the skin, hair and iris. Although albinos have poor vision yet they lead normal life. On the basis of principles of simple recessive inheritance, the probability of albinic child from a normally pigmented parent, will be 1/4 or 25 %.
