Cooing and babbling are early stages of speech development. As babies get older (often around 9 months), they begin to string sounds together, incorporate the different tones of speech, and say words like mama and dada (without really understanding what those words mean).
The map distance between two genes, measured in centimorgans or map units, equals the percentage recombination frequency between the two genes--the likelihood of offspring with copies of those genes on the same chromosome that come from different parents.ave. dna image by Allyson Ricketts from Fotolia.com. The concept of map distance in a genotype refers to where genes are located on a chromosome but does not refer to physical distance; rather, map distance refers to the tendency for a crossover to occur between genes.
The distance between the two points is 5sqrt2. To find the distance between the points, first start with determining the distance between the 'y' components and the 'x' components. This distance is known as: y_2-y_1 or x_2-x_1 Using these equations, we can plug points 1 (2,3) and 2 (-3,-2) in. We get -5 for the both the distance between the 'y' components and the 'x' components.
