Answer: The answer is mutation and natural selection
Explanation:
When members of a population interbreed (marry one another), genes are recombined and spread in the entire population resulting in gene flow. However, the Dunkers family decision not to intermarry would prevent gene flow, rather favor the NATURAL SELECTION of some genes, making the DUNKERS family genetically unique from the remaining population
Answer;
Both genes and the environment

Explanation;
-Human behavior is determined by complex interactions of both nature and nurture. Genetic make up of a person together with the environment influences the physical and behavioral characteristics of an individual.
-Personality is a complex trait that is influenced by many different genetic and environmental factors. Personality traits are also polygenic trait because multiple genes are involved in determining these traits. Because a large number of genes each playing a small role in determining our personality, it is difficult to isolate and identify these genes.
Answer: Grassland is the biome which is characterized by it's lack of trees, warm temperatures, and it's moderate rainfall.
Grasslands are generally open and continuous, flat areas of grass. They are often found between temperate forests at high latitudes and deserts at subtropic region. Grasslands lack trees, due to poor infilteration of soil, too deep water table or water table is too high, very thin layer of soil over hard rock, soil is acidic in nature, poor in macronutrients and low presence of organic matter. The climate in grasslands varies, but natural grasslands are generally hot and dry. The amount of rainfall received by grasslands depends about the level where they are situated. The amount of rainfall received by grasslands is lower then tropical forests and higher than deserts. Therefore, grasslands receives moderate rainfall.
Answer:
Farming affects biodiversity as it needs space and chemicals.
Explanation:
Farming requires space, so it firstly contributes in the habitat loss of many plants and animals species that were already present there. Then seeds are sown to grow the desired
