Genetics

1. When an egg cell and a sperm cell combine to develop an offspring
3. A characteristic or feature
4. a type of molecule in our food that our bodies need. Example actin and myosin
7. having two of the same allele for a gene.
10. A certain region of a chromosome that causes a certain protein to be made; is sometimes related to a certain trait( like the MSTN gene is connected to muscular).
11. A trait that is always expressed when at least one dominant allele is present. It is represented by a capital letter.
13. The specific instructions found in DNA that determines traits, such as eye color, hair type, or height. It tells cells what proteins to make and how the body should develop.
14. An organism profile of an individual’s chromosomes. One set of chromosomes and all of the other sets of somatic cells
16. The combination of alleles an individual has. Typically represented by letters. Capital or lowercase.
18. having different alleles for a gene.

2. A common feature of most cells that is copied when most cells are made; they are physical structures that are passed from parents to offspring in egg and sperm cells
5. A common feature inside most cells; the nucleus is where chromosomes are located inside the cell
6. A trait that is only expressed when two recessive alleles are present. It is represented by a lowercase letter.
8. The material inside the cells that carries the instructions for how living things grow, look and function. In most living organisms, this material is DNA.
9. Difference within a trait
12. an original (model) of biological relationships
15. Different forms of genes that cause different forms of proteins, which lead to variations in a trait, like extra big muscled or typical muscles
17. the way an individual look for a specific trait
