- 4. Genetics is the branch of biology that studies how traits are inherited from one generation to the next. I
- 7. Alternative forms of a gene that result in different traits.
- 8. Genotype refers to the genetic makeup of an organism, which includes the combination of alleles present for a particular trait. It represents the genetic information that an individual carries and is written in the form of letters.
- 9. Artificial selection, also known as selective breeding, is the process of intentionally choosing and breeding organisms with desirable traits to produce offspring with those traits. This method has been used by humans for centuries to modify and improve various plant and animal species.
- 10. Molecule present in all living things; contains the genetic information that determines the traits that an organism inherits and needs to live
Down
- 1. Chromosomes are thread-like structures found in the nucleus of cells that carry genetic information in the form of DNA. They contain genes, which are the units of heredity responsible for specific traits.
- 2. Gametes are specialized reproductive cells, such as sperm and eggs, that carry half the number of chromosomes found in other cells of an organism. They are produced through a process called meiosis and are involved in sexual reproduction.
- 3. Heredity is the passing on of traits from parents to offspring through genetic information. It is the reason why offspring often resemble their parents and share certain characteristics.
- 5. Genes are a segment of DNA and the basic units of heredity and determine the traits and characteristics of an organism.
- 6. A dominant allele is an allele that is expressed or observed as a trait when present in either one or both copies in an individual's genotype. It masks the expression of a recessive allele when both are present.
