<span>The law of segregation is a principle of Mendelian genetics. The law of segregation occurs during meiosis when gametes are formed. At this time, the alleles for each gene segregate from one another. As a result, each gamete contains only one allele per gene. Thus, the gametes are haploid. The gametes need to be haploid so the specie’s diploid number is maintained when the egg and sperm unite. As a result of the law of segregation, each diploid parent passes a random allele for each trait to his/her offspring during fertilization. Thus, segregation increases variation within a species.</span>
Answer:
Adaptive alleles that are beneficial in one environment can be deleterious in another, due to selective pressures.
Explanation:
just took the quiz.
The correct answer is A.
Water runoffs usually carry nutrients especially fertilizers from off the landscape and washed them into the wetlands and other water bodies. Phosphorus is a common ingredient that is present in all fertilizers. Phosphorus acts as a pollutant in these water bodies and put the organisms living in the water bodies at risk. High concentration of phosphorus causes rapid growth of plants in the wetlands and lead to depletion of oxygen leading to the death of organisms living in the wetlands.
Due to this occurrence, the Florida government has taken steps and enact several laws to ensure that the phosphorus pollution is arrested in order to preserve the wetlands.
