You can use a linnet square if you know the genotypes of their parents
This response is important because it enables the plant to increase its intake of carbon dioxide. Carbon dioxide is an important gas,during the process of photosynthesis, where plants use energy from sunlight to make simple sugars and release oxygen. This is also a way of absorbing carbon dioxide (a green house gas) from the atmosphere thus reducing its amounts.

Explanation:
Answer:
A. Heritable
C. Affected by the MC1R gene
D. Polygenic trait
Has evolved due to evolutionary processes such as natural selection.
Explanation:
Human skin color is a polygenic trait as it is regulated by more than one gene. Each allele of these genes has an additive effect on the overall skin color of an individual. Therefore, the trait is a continuous trait, not a discrete one. The genes for human skin color are transmitted from parents to progeny which in turn makes it a heritable trait.
The gene MC1R codes for melanocortin 1 receptor and thereby, regulate the skin color of humans since melanocyte-stimulating hormone binds to the receptor to trigger the synthesis of melanin from melanocytes. Evolution of various skin color in human beings is regulated by natural selection which in turn favors the skin tone best suited under the prevailing climatic conditions of a particular human population
