Genetics

2. A very fine thread or threadlike structure.
6. A small or immature
7. A diagram used in genetics to visually represent all possible combinations of alleles.
11. When an egg cell and a sperm cell combine to develop an offspring.
12. Different forms of genes which can cause different forms of proteins which lead to variations in a typical muscle.
14. A certain region of a chromosome that causes a certain protein to be made.
17. An organized profile of an individual’s chromosomes.
18. A characteristic or feature.
19. A type of inheritance in which the alleles from each parent blend together to form a mixed phenotype in the offspring.
20. Having different alleles for a gene.
21. A trait that is only expressed when two recessive alleles are present.
22. The part of the stamen of a flower that produces and contains pollen and is usually borne on a stalk.
23. A permanent change in the DNA sequence of an organism.
24. The manner in which something is expressed or performed.
26. A type of molecule in our food that our bodies need.
27. One of a pair of female glands in which the eggs form and the female hormones estrogen and progesterone are made.

1. Having two of the same alleles for a gene.
3. A common feature inside most cells; the nucleus is where the chromosomes are located inside the cell.
4. Differences within a trait
5. An original representation (model) of biological relationships.
8. A trait that is always expressed when at least one dominant allele is present.
9. The female organs of a flower.
10. A molecule that contains genetic information for an organism’s development and function.
13. A condition wherein the dominant allele completely masks the effect of the recessive allele.
15. A common feature of most cells that is copied when new cells are made; they are physical structures that are passed from parents.
16. The way in individual.
