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?

Researchers in the Netherlands studied the effects of parental care giving in European kestrels over 5 years. The researchers transferred chicks among nests to produce reduced broods (three or four chicks), normal broods (five or six), and enlarged broods (seven or eight). They then measured the percentage of male and female parent birds that survived the following winter. (Both males and females provide care for chicks.) Which of the following is a conclusion that can be drawn from this graph?

What does the study of analogous organ tell us about evolution?

A. This is the example of convergent evolution, occurred due to different group of organisms inhabiting same environments

B- Evolutionary change follow common pathway in two or more distinct species

C- Different organism get adopted to one environment

D- Similar group of organisms with mutations and variations getting naturally selected in different environments
