Consider the ABO “blood type” gene. This single gene has three alleles called A, B, and O. There are four resultant “blood types” (phenotypic classes), as follows:C

                               

Assume Hardy-Weinberg equilibrium. In Norway, the frequencies of the A and B alleles are 0.26 and 0.07, respectively. What is the frequencies of these six genotypes (AA, AO, BB, BO, AB, and OO);

Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Arrange in the order of their increasing capacity:

In the plants, due to mutation in the mitochondrial genome causing cytoplasmic male sterility can be influenced by the nuclear gene (Rf),  which is dominant over the cytoplasmic mitochondrial genome. If a male sterile plant  is pollinated by the fertile male plant with homozygous (Rf)condition, the progeny obtained in F1 will have
