nata0808 [166]
The correct answer for this question is A. Law of segregation.

All individuals have two alleles for a  given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.  

Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.

rjkz [21]
One negative impact of building a dam could be that it affects natural habitats of animals who live in and around the river. When you build a dam, the river's height becomes smaller because a huge amount of water becomes technically removed or blocked. This can affect animals such as fish or beavers or anyone who needs that water.
