In biology, what is the basic level of organization?

organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere

20

It produces a distortion in normal Mendelian segregation, so that chromosomes bearing this gene are over-represented in an organism's offspring.

Segregation distortion

15

It refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the actor.

Altruism

15

Does natural selection ever favor groups, rather than individuals?

No

15

True or False. The discussion of units of selection aims to find out which level natural selection directly acts on, and which ones it affects only incidentally.

True

15

In organisms like humans, with separate germ and somatic cell lines, selection between cell lines is a strong force. (T/F)

False

15

Group selection, in which selection produces adaptations for the benefit of groups of unrelated individuals, is thought to be a weak force.

True

15

Adaptations evolve because they increase the replication of genes. (T/F)

True

15

When a lion hunt is successful, does the genus Felis benefits? (Y/N)

Yes

15

What form of adaptation does this Papilio butterfly shows?

Mimicry

15

What form of adaptation does the stick insects shows?

Camouflage

15

What are the three theories have been put forward to explain the existence of adaptation?

supernatural creation, Lamarckism, and natural selection

15

A possible example of concept is bird feathers: although obviously valuable for flight, it has been suggested that they were originally an adaptation for insulation

preadaptation

15

Is perfect adaptation possible?

No

5

Adaptations in nature are not perfect, for various reasons. Give atleast one reason

time lag, developmental constraint, genetic constraint, historical constraint

15

A plant, for example, may be more likely to mutate to a new form with more branches than would a vertebrate because it is easier to produce that kind of change in the development of a plant. What type of constraint is this?

developmental?
