Autosomal recessive diseases are genetic diseases that are passed to a child through both parents' chromosomes. Each person inherits 23 chromosomes from each parent and so has 23 pairs of chromosomes. Each chromosome contains genes.One or both of the chromosomes in a pair may contain a changed (mutated) gene that could cause a genetic disease. In an autosomal recessive disease, both chromosomes in a pair must have a changed gene for the person to have the disease.If only one chromosome has a changed gene, the person is a carrier and does not have symptoms.ach person inherits 23 chromosomes from each parent and so has 23 pairs of chromosomes.

1 An asphalt driveway typically costs about $2 -$5 a square foot, $1,200 - $3,000 for a 12'x50' single-car driveway; or $25,000 -$50,000 for up to a quarter mile. Do-it-yourself supplies can cost $50 -$200 depending on the size and condition of the driveway, and the quality of the sealer. 2  Professional driveway sealing can cost $200 -$500 or more.
To calculate the asphalt driveway cost, you just need to take a measurement of length x width to get the approximate square foot area, and multiply it by the average cost of $3-$4/square foot. Example: A driveway thatâs 10â² wide and 60â² long equals 600 square feet.t that approximate cost, a driveway contractor will dig out 4-6 inches of whatever you already have in place, replace it with clean driveway gravel and grade it to a level and compacted surface. After that, they will put down 3-4 inches of base asphalt, and a final coating of 1-2 inches of topcoat.
