#Unit 8. Inheritance Biology
In cats, blood-type A results from an allele (IA) that is dominant over an allele (iB) that produces blood-type B. There is no O blood type. Two heterozygous was intercross. What is the probability of first offspring blood-type B?

#Unit 1. Molecules and their Interaction Relevant to Biology
Choose correct statements about ‘Protein Disulfide Isomerase’ in protein folding
A. Oxidized PDI catalyzes the rearrangement of a polypeptide’s non-native disulfide bonds via disulfide interchange reactions to yield native disulfide bonds.
B. Reduced PDI catalyzes the initial formation of a polypeptide’s disulfide bonds through the formation of a mixed disulfide.
C. Protein disulfide isomerase contains the conserved active site motif of Cys-Xaa-Xaa-Cys found in thioredoxin and shares a similar role to the Dsb family of proteins found in E. coli.
D. Under more reducing conditions with thiols in the active site the enzyme reshuffles disulfides (isomerase) in target proteins.

#Unit 11. Evolution and Behavior
Sexual dimorphism (SD) is a pattern that is seen throughout the animal kingdom and differences between the sexes in coloration are common in many organisms. Following some statement are given
A) There are many mechanisms that drive the evolution of SD, the most accepted mechanism being sexual selection
B) Mate choice is an important proximate mechanism of sexual selection, often the sex with the higher reproductive investment is the ‘choosy’ sex
C) Larger species are more sexually dimorphic than smaller species
D) Terrestrial species tend to be more sexually dimorphic than arboreal species
