The following experiment is designed to study the role of several hormones in the regulation of metamorphosis in frogs.

Group #	Treatment	Days to Metamorphosis
1	Saline	30
2	Prolactin	> 100
3	TSH	15
4	Thyroxine	10
5	Corticosterone	30
6	Thyroxine + Corticosterone	5
7	Prolactin + TSH	30
8	Thyroid gland removed	> 100

These results suggest which of the following about prolactin (group 2 and group 7) at the dose tested?

The frequencies of two allele’s p and q for a gene locus in a population at Hardy-Weinberg equilibrium are 0.6 and 0.4, respectively. After a few generations of inbreeding, the heterozygote frequency was found to be 0.10, The inbreeding coefficient in this case is

polymorphism is define existence of two or more form of same species within same population at the same time and place .polymorphism either balanced or transient depending upon type of natural selection  which of the following reason for balanced genetic polymorphism

a. each morph has selective advantage at equal intensity

b. non of the morph has selective advantage over other

c. heterzygote superiority

#Question id: 3381

#Unit 9. Evolution & Diversity of Life Forms

A source population with allelic frequency of p and q is .90 and .10 respectively. Recipient population with 900 individuals having allelic frequency of p and q is .30 and .70 respectively. If 100 migratory individual is inter from source to recipient population. After migration what is allelic frequency of p in their recipient population?
