Explain how the chromosomal theory of inheritance to advance our understanding of genetics.

Explanation:

The  Chromosomal Theory of Inheritance, basically answer the question: where are genes found in a cell?

It was described by Sutton and Boveri between 1902-1903 and states that individual genes are found at specific locations on particular chromosomes. It also postulates that the behavior of chromosomes during meiosis can explain why genes are inherited according to Mendel’s laws.

It states:

- Chromosomes, like Mendel's genes, come in matched (homologous) pairs in an organism:  one member comes from the mother and one from the father.

- The members of a homologous pair separate in meiosis, so each sperm or egg receives just one member. This is referred as the law of segregation.

-The members of different chromosome pairs are sorted into gametes independently of one another in meiosis.

this is math not biology xd

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
