Following statements are regarding to regulation of S phase and mitotic cyclin levels in budding yeast.

A. In late anaphase, the anaphase-promoting complex (APC/C) ubiquitinylates S phase and mitotic cyclins.

B. In late anaphase, the anaphase-promoting complex (APC/C) phosphorylates S phase and mitotic cyclins.

C. During exit from mitosis and G1, Cdh1 is dephosphorylated and active; during S phase and mitosis, Cdh1 is phosphorylated and dissociates from APC/C, and APC/C becomes inactive.

D. During exit from mitosis and G1, Cdh1 is phosphorylated and active; during S phase and mitosis, Cdh1 is dephosphorylated and dissociates from APC/C, and APC/C becomes inactive.

E. The G1/S phase CDKs, which themselves are not APC/CCdh1 substrates, phosphorylate Cdh1 at the G1–S phase transition.

F. The G1/S phase CDKs, which themselves are not APC/CCdh1 substrates, ubiquitinylates Cdh1 at the G1–S phase transition.

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

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?
