Answer:
Because the have similar limbs.
Because they have similar functions.
Explanation:
(because they have similar limbs)
Homology (evolution) describes a structure that has similar function like limbs on dogs and bears (used for walking) and also have a similar arrangement of bones. The fins on a doplhin might be different from the wings on a bat but they reflect a common origin due to their bone composition e.g carpals and radius bones.
(because they have similar functions)
Analogy (evolution) describes a structure with for example, bird and butterfly wings that have no common ancestor but have the same purpose, in this case flying. They developed independtly as adaptions. This supports natural selection which is a driving force for evolution.
O allele 60 + 60+30 = 150
o allele
30 + 10+10 = 50
O allele frequency = 150/200 = 0.75
Thus, the O allele frequency is 3/4 or 0.75
o allele frequency = 50/200 = 0.25
The o allele frequency is 1/4 or 0.25

FULL ANSWER
DNA is found within chromosomes. When a cell divides, or replicates, the DNA is copied. RNA comes into the picture when it is time to copy the DNA and send it to the cytoplasm of a cell, where protein synthesis takes place. DNA can't copy itself without RNA present and several types of RNA are used to copy and transmit genetic information. A good example of how DNA and RNA work together is a newborn baby's development. Without the relationship between RNA and DNA, a single sperm and egg couldn't produce a baby which has five trillion cells, each of which carries the same DNA.
