NEET BIOLOGY

Detailed explanation-1: -Genetic variation-these are differences between individuals that are inherited from parents, such as the colour of your eyes, hair and skin. Environmental variation-these are differences between individuals that are not inherited but caused by the environment that the organism lives in, including scars and tattoos.

Detailed explanation-2: -Environmental causes of variation Characteristics of animal and plant species can be affected by factors such as climate, diet, accidents, culture and lifestyle. For example, if you eat too much food you will gain weight, and if you eat too little you will lose weight.

Detailed explanation-3: -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 survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-4: -In addition to demographic processes, ecological and environmental factors can also play a role in shaping genetic diversity patterns (Gaggiotti et al.
