Two chromosomes out of these are sex chromosomes. A female has two X chromosomes, while a male has one X and one Y chromosome.
The gametes egg and sperm have only one set of chromosomes. The unfertilised egg always has one X chromosome.
But sperms are of two kinds—One having X chromosome, and the other having Y chromosome. When a sperm containing X chromosome fertilises the egg, the zygote would have two X chromosomes and develop into a female child. If the sperm contributes a Y chromosome to the egg or ovum at fertilisation, the zygote would develop into a male child. It is thus also clear that the sex chromosomes of the father determine the sex of an unborn baby.

In this part of the book, the line that appears again and again is, "There were these things to do. In the first few weeks after the plane crash Brian focused on the world in which he used to live, constantly seeking and hoping for a way out of his situation. He remained relatively immobile because he thought his stay in the woods would be short-term, and because he pitied himself. In this part of the book, on the other hand, Brian accepts that it may be some time before he leaves the woods.
Starting to adopt a more active and positive outlook and steering clear of self-pity, Brian makes efforts to gather food, make fire, and perfect his tools. These efforts also hint that he now looks toward the future and prepares for what it might hold.
His hunger for hamburgers and for similar urban conveniences wanes, a new hunger taking its place. Paulsen writes, "This was hunger that he knew would be there always, even when he had food—a hunger that made him look for things, see things. A hunger to make him hunt.

Chapter 11 Brian occupies himself by storing the eggs, cleaning his camp, and stacking wood; these activities help keep him from falling into depression. Chapter 12 Brian spends many hours perfecting his fish spear, but in the end it fails to help him catch any fish. He asks the team to give him just one game of good offense. Michael has a lot to learn on the football field. Coach Orgeron gathers his players around him and energizes them for the game tomorrow.
He emphasizes the rivalry between Mississippi State and Ole Miss, and encourages the team to fight for a win. Lewis notes the tension in the room: Coach Orgeron is the only white person there.
To this day, the book implies, black students are discriminated against at Ole Miss, in spite of their status as elite athletes. The next morning, the Ole Miss team travels out to Starkville for the game, which ends disappointingly. Ole Miss starts out strong, but then the team gets into trouble: the Ole Miss quarterback keeps getting blitzed by Mississippi state, and soon Mississippi State leads 21 to 7.
It is becoming clear that Ole Miss lacks a coach with the genius of Bill Walsh —someone who can maximize the players potential. The players grow increasingly disorganized and unsure, and DeLeone radios Michael to try harder. Invigorated by this encouragement, Michael plays even harder, hitting the weight room and losing twenty-five pounds of fat. Michael responds well to encouragement, putting in longer hours at the gym to improve his performance on the field.
In spite of his new success, Michael Oher continues to feel lonely and insecure about his family. He goes to visit Denise , but when he arrives, he finds the police arresting his mother for driving a stolen car.
For unclear reasons, the police also arrest Michael; Sean guesses that they do so because of racism, pure and simple. His three closest friends hail from poor black neighborhoods, do poorly in their classes, and have children.
For Thanksgiving, Michael invites a friend, another freshman football player who comes from a similar background, to dinner with the Tuohys. Michael continues to face discrimination because of his race and his big, intimidating appearance. However, he bonds with other students with a background similar to his own. One day, toward the end of freshman year, Michael clashes with a freshman linebacker named Antonio Turner.
Michael threatens to hit Antonio; Antonio flees to another building, and Michael follows him, and then beats him senseless. Afterwards, Michael sees a little boy—the three-year-old son of a college tutor—lying on the floor in a pool of blood. Somehow, in the fight, the boy has been injured. Leigh Anne starts to drive out to Ole Miss, but then realizes she has no idea where to look for Michael.
