Answer:
Evolution - It occurs due to the continuous variations and diversifications coming from the past generations
Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!
Evolution - Driven by natural selection
Natural Selection- Driven by new characters that are the results of mutations
Evolution - Duration of Action Acquires millions of years
Natural Selection - Can be done in a short duration
Evolution - Example ;- Darwin’s finches, bright-colored peacocks, Mexican cavefish, etc.
Natural Selection -Example ;- Tree-frogs are mostly eaten by snakes, giraffes with short and long necks, etc.
They have a deficiency of B vitamins which comes from red meat.
Answer:
If the man has blood type A one of whose parents had blood type O then he must be having the genotype IAi and the woman with blood group AB would have genotype IAIB. So if they produce offspring than the putative genotype of the offspring would be IAIA, IAi, IAIB, and IBi.
IA i
IA IAIA IAi
IB IAIB IBi
Therefore out of four offspring, two offspring would be having A blood group, one offspring would have AB blood group and one offspring would have B blood group.
