Answer no 1)
<em>The correct option is f) b, c</em>
Explanation:
By the method of sexual reproduction, every organism on the earth acquires a gene pool or allelic variations which make him/her different from other organisms. The specific genotype is destined for the specific individual only and no other individual will ever acquire the exact similar genotype. Sexual reproduction is the means by which genetic variations can be produced among parents and offsprings whereas asexual reproduction is the method by which organisms with similarities are produced.
Answer No 2
The correct options are a,c
Explanation:
Cryptic genetic variations can be described as a type of variations which arise from a genetic variation that does not contribute to the normal range of phenotypes observed in a population, but that is available to modify a phenotype that arises after environmental change or the introduction of novel alleles. Although evolution is an obvious phenomenon, yet the process of evolution is very slow and takes a lot of time.
Answer No 3)
The correct option is d) There is no specific rule for the origins of elaborate, detailed adaptive behaviors in non-human animals; all animal behavior depends on cultural learning, genetic design information, and individual experience.
Explanation:
Non-humans animals learn some of their adaptive behaviours due to their genetic make up. Both the environment and the genetic make up of the non-human animals is essential in predicting the adaptive behaviour of an animal. Animals also tend to behave by copying other organisms of the same species or by learning from individual experiences. Hence, the correct option is d.
Answer No 4
The correct option is B) Male lion infanticide evolves because it is likely to increase the average fitness of the local lion population by eliminating less fit individuals.
Explanation:
Infanticide can be described as a phenomenon in which a parent, either male or female, kills his/her own child due to certain reasons.
Infanticide reduces intraspecific competition and also increases the parental investment afforded to their own young, and allows females to become fertile faster. Hence, the correct option is B.
Answer No 5)
The correct option is a,c
Explanation
Kin selection results in the optimal level of cooperation for the benefit of the gene pool represented by the animals engaging in such cooperation.
Kin selection results in the optimal level of cooperation for the benefit of the species of the animals engaging in such cooperation.
Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction.
