<span>Critical thinking and inferences are both ways to come to a conclusion or decision. Both are used in everyday life to come to a decision about a particular situation. An inference is more similar to an assumption though. You don't spend as much time considering all aspects of the situation. An inference is more of a quick decision. When you engage in critical thinking, you consider all aspects of the decision. Critical thinking would take more time.</span>
Answer:
crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis . At that stage each chromosome has replicated into two strands called sister chromatids. The two homologous chromosomes of a pair synapse, or come together. While the chromosomes are synapsed, breaks occur at corresponding points in two of the non-sister chromatids, i.e., in one chromatid of each chromosome. Since the chromosomes are homologous, breaks at corresponding points mean that the segments that are broken off contain corresponding genes , i.e., alleles. The broken sections are then exchanged between the chromosomes to form complete new units, and each new recombined chromosome of the pair can go to a different daughter sex cell. Crossing over results in recombination of genes found on the same chromosome, called linked genes, that would otherwise always be transmitted together. Because the frequency of crossing over between any two linked genes is proportional to the chromosomal distance between them, crossing over frequencies are used to construct genetic, or linkage, maps of genes on chromosomes. Mutations , temperature changes, and radiation all affect crossing over frequency. Under the microscope, a crossover has the appearance of an X and is called a chiasma.

Answer:
<em>The correct option is d) None of the answer options is correct.</em>
Explanation:
Option A is not correct because dominant traits are not only common to females. Males can also have these traits as common as females.
Option B is false because not all the offsprings can have the chance of being affected. For example, if the parent carrying the disease is heterozygous for the trait then not all offsprings will have the chance to have that disease.
Option C is false because not all dominant traits are common. Sometimes, a recessive trait is more common than the dominant trait.
