Question
Why are variations that are advantageous are more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because the trait is an acquired trait.
Because they come from recessive alleles.
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because the trait is an acquired trait.
Because they come from recessive alleles.
Hint:
- Variations are the differences in the genetic makeup or phenotype of various organisms.
The correct answer is: Because they are more likely to survive and reproduce.
- Variations are the differences in the genetic makeup or phenotype of various organisms.
- Variation arises due to crossing over, recombination, mutation & environmental effects on the expression of genes present on chromosomes.
- Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual to survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
