Answer:C) Traits like this are determined by the genes passed from parents to their children.
Explanation: Every trait in an organism is controlled by a pair of gene. A gene that controls a trait usually have two alleles. During fertilization, for every pair of gene one allele is inherited from the mother while the other allele is inherited from the father and the two alleles come together to form a pair of gene. Every trait in an organism is determined by genes that are passed from the parents to the offsprings.
Genetic Variation
Natural selection results in organisms that are better suited to their environment are able to pass on genes to create strong offspring
