#Unit 8. Inheritance Biology

Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?

Biosynthesis of all N-linked oligosaccharides begins in the rough ER with a preformed branched oligosaccharide precursor Glc3Man9(GlcNAc)2, Which of the following statements is incorrect about these biosynthesis?
a) the oligosaccharide precursor is assembled on a membrane- attached anchor called dolichol phosphate
b) First sugar residue is attached to dolichol by a glycosidic bonds & the other
sugars are added by high-energy pyrophosphate
c) Two N- acetylglucosamine (GlcNAc) and five mannose residues are added one at a time to a dolichol phosphate on the lumen
d) Four mannose and three glucose  residue are added one to a dolichol phosphate on the luminal side

Eutrophication is often caused by excess limiting-nutrient runoff from agricultural fields into aquatic ecosystems. This process results in massive algal blooms that eventually die and decompose, ultimately depleting the dissolved oxygen, killing large numbers of fish and other aquatic organisms. Predict which of the following human actions would best address the problem of eutrophication near agricultural areas?
