Genes a, b, and c are known to be in that linear order in an organism. A testcross is done that yields 20 double crossover proge
larisa [96]

Answer:

Explanation:

The observed frequency of the double crossovers (DCOs) is 20/1000, or 0.02. If there is no interference then this will be the same as the expected, which is just the product of the single crossover frequencies, that is, SCO frequency (a-b) x SCO freq. (b-c) = 0.02.

(a) Any combination of map distances whose product (a-b) x (b-c) = 0.02 is possible. However, three are most likely:

a 20 mu b 10 mu c

a 10 mu b 20 mu c

a 14.14 mu b 14.14 mu c

(b) The distances would be exactly the same.

(c) The expected number of DCO progeny would be 17.

p = m / V    (Density = Mass / Volume)

p = m / (w * l * h)        (Density = Mass / [Width * length * height]) (V = w * l * h)

p = 120 / (5 * 4 * 3)      (Mass = 120g [Given]      w=5 l=4 h=3 [Given])

p = 120 / 60

p = 2 g/cm^3

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
