Câu 17: GED Section 3 Science: Section Three Science

In humans, a pair of chromosomes (one from each parent) determines the sex of the baby. Females have two X chromosomes, while males have an X and a Y chromosome. The baby always gets an X chromosome from the mother, so in humans, the father determines the sex of the baby by supplying it with either an X chromosome to make it female, or a Y chromosome to make it male. In birds, like in humans, a pair of chromosomes determines the sex. Birds with two W chromosomes are male. Birds with a W chromosome and a Z chromosome are female. Which statement is true about birds?

1. A. The male bird determines the sex of the offspring by supplying it with the W or the Z chromosome.
2. B. The male bird determines the sex of the offspring by supplying it with one of its W chromosomes.
3. C. The male bird determines the sex of the offspring by supplying it with the X or the Y chromosome.
4. D. The female bird determines the sex of the offspring by supplying it with the X or the Y chromosome.
