a. The first meiotic division results in the segregation ofsister chromatids into daughter cells.
b. Polar bodies are only observed in male meiotic divisions.
c. The second meiotic division results in a reduction inchromosome number from diploid to haploid.

If the cyclins that control the transition between S & G2phase have been inactivated. Which of the following scenarios wouldbe the MOST LIKELY result?
Select one:
a. Cells would enter M phase where errors in DNA replicationwill be corrected.
b. Cells would progress through the rest of the cell cyclewithout any problems.
c. Cells would enter M phase containing errors following DNAreplication that will not be corrected.
d. Cells would not enter M phase at all and would be pushed intoG0 phase.
Two genes are required for the determination of hair colour inguinea pigs:
i. One for the production of the coloured pigment (where P encodesblack pigment which is dominant over p for grey pigment)
ii. Another gene is required for the fixation of the pigment to thestrand of hair (where F is dominant and fixes the hair pigment,while f is recessive and does not fix the hair pigment).
Therefore, the F gene is epistatic to the P gene. In an individualwho is albino (i.e. has no hair colour at all), which of thefollowing genotypes is MOST LIKELY?
Select one:
a. ppFf
b. PPFF
c. PpFf
d. Ppff

b. 25% A; 25% B; 50% AB
c. 100% AB
d. 25% A; 50% B; 25% AB
