How many genes are in the human body? How many autosomal recessive diseases in humans are there? The probability that a child will inherit a recessive trait is 1/4. If the parents have 4 children, what is the probability that their third child will inherit the recessive trait?
How many genes does the Human Genome contain? The Human Genome Project has revealed that there are probably about 20,000-25,000 'haploid' protein coding genes. The completed human sequence can now identify their locations. But only about 1.5% of the genome codes for proteins, while the rest...

We also know that functional differences between duplicate genes can originate in several different ways, including mutations that directly impart new functions, subdivision of ancestral functions and selection for changes in gene dosage. Interestingly, in many cases the 'new' function of one copy is...

Figure 1. The meta-analytic Pareto front of markers: a trade-off between coverage and signal-to-noise ratio (A) Ideal markers have high coverage (high expression in cells of interest) and high signal-to-noise ratio (relatively low expression in background cells). (B) Fraction of genes inc...
