D. Genetic Variation
Explicación
## Step 1The problem is asking us to identify what the processes of crossing over, mutations, the Law of Segregation, and the Law of Independent Assortment all lead to an increase of. ## Step 2Crossing over is a process that occurs during meiosis where two chromosomes pair up and exchange segments of their genetic material. This results in new combinations of genes, which increases genetic variation.## Step 3Mutations are changes in the DNA sequence of an organism's genome. These changes can be beneficial, neutral, or harmful. Beneficial mutations can lead to new traits that can increase an organism's fitness, thus increasing genetic variation.## Step 4The Law of Segregation, proposed by Gregor Mendel, states that allele pairs separate independently in the formation of gametes. This means that each gamete carries only one allele for each inherited trait. This separation of alleles increases genetic variation.## Step 5The Law of Independent Assortment, also proposed by Mendel, states that genes for different traits can segregate independently during the formation of gametes. This means that the inheritance of an allele for one trait does not affect the inheritance of an allele for another trait. This independent assortment increases genetic variation.
