Why are advantageous traits more likely to be passed onto offspring

For the sake of continuous life flow, advantageous traits are more likely to be passed onto offspring

Explanation:

Advantageous traits are the traits that have helped the parents to survive in adverse condition. These advantageous traits being helpful in survival are passed on to the next generation so that they can also survive and reproduce fertile and viable offspring.  

As per Darwin’s theory an organism develop advantageous traits to be fit among its group member and hence survive and reproduce.

For the sake of continuous life flow, advantageous traits are more likely to be passed onto offspring

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
