Crossing over is the main event in meiosis and heredity as it leads to genetic variation.
<h3>What is genetic variation?</h3>
Genetic variation is the changes that take place in the genes of individuals that can lead to the formation of new characters.
it generally occurs in meiosis specifically during crossing over.
Thus, it can be concluded that crossing over between non-sister chromatids during meiosis is significant in heredity as it leads to genetic variation.

Answer:
25 nucleotide sequence pair
Explanation:
There are four nucleotide sequence pair present in DNA. and if we have 100 nucleotide so 25 nucleotide sequence pairs will be formed and each pair contains adenine (A), cytosine (C), guanine (G), and thymine (T).
Cytosine nucleotide paired with guanine nucleotide and Adenine nucleotide paired with thymine nucleotide . They have hydrogen bonds between each bases.
Answer:
This phenomenon is known by neuroscientists as Neuroplasticity, or brain plasticity
Explanation:
Think of plasticity, Neuroplasticity, or brain plasticity, is the simplest terms, as the ability of parts of the brain to adapt their function or ability to change throughout life.
Structural plasticity - brains ability to change in response to the environment.
Functional plasticity-brains ability to change in response to the activities.
d. The mutation will be expressed only if the individual has two copies of the recessive allele.
