Your answer is correct. The size of an organism is most likely determined by both its genes and its environment. Let me explain how we can arrive at this conclusion.
Size is a complex trait that can be influenced by genetic factors as well as environmental factors. Genes provide the blueprint for an organism's development, including its growth and physical characteristics. Different genes can contribute to variations in size among individuals of the same species. For example, some genes may promote rapid growth, while others may inhibit it.
However, the environment also plays a crucial role in shaping an organism's size. Environmental factors such as nutrition, temperature, access to resources, and competition for resources can impact an organism's growth. For instance, an organism with ample food resources is more likely to grow larger compared to one with limited access to sufficient nutrients.
To further support the idea that both genes and the environment influence size, we can consider twin studies. Twin studies involve comparing the size of genetically identical individuals raised in different environments. These studies consistently demonstrate that even when individuals share the same genetic makeup, their size can vary depending on their environment.
Therefore, based on these explanations and the understanding that genetics and the environment interact to shape an organism's size, we can conclude that the most likely determinant of size is a combination of both genes and the environment (Answer choice 3).
