Answer/Explanation:
DNA replication doubles each chromosome, meaning the cell can pass on DNA to daughter cells - the duplicated DNA is divided equally between the two new cells formed from the parent.
The laws of inheritance are:
1) The Law of Dominance: An organism with alternate forms of a gene, called alleles, will always display the form that is dominant, masking the recessive trait.
2) The Law of Segregation: In a diploid genome, like most eukaryotes, each trait is defined by a pair of genes (alleles). Each allele is randomly passed on to the gametes so that each gamete only contains one allele. The offspring inherits one allele from each parent during the process of fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted independently from one another That is, the inheritance of one trait does not depend on the inheritance of another trait. so that the inheritance of one trait is not dependent on the inheritance of another.
The guard cell is responsible for controlling the size of the stomata in leaves. These do so as a result of an interaction between potassium ions and water in and around the cells. When potassium ions accumulate inside the guard cells the water potential inside these cells is lower than that of the outside and as a result, water has to be taken in. This makes the guard cells turgid which in turn stretches them and results in the opening of the stomata. Meanwhile, when potassium ions accumulate outside the cell, the opposite scenario results. Water from inside the cell moves out, making the guard cells flaccid, thus causing these to cover (and effectively close) the stomata.

Answer:
Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.
