How does polygenic inheritance differ from mendelian inheritance

Mainly, the number of genes that control traits.

Explanation:

Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.

Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.

Mendelian inheritance would assume that the offspring would either be fair or dark only.

Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
