Thabo travelled a distance of 100 km in 2 hours .Calculate his average speed​

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.
