Genetics

1. Regulates gene expression and controls cellular activities
3. Is the entire complex of DNA and proteins that is the building material of chromosomes
5. Double-membrane-bound organelles that produce energy through cellular respiration
9. Determined by both genetic makeup and environmental influences
10. Membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum
13. An allele that only expresses its trait when two copies are present
14. A membrane-bound organelle that contains digestive enzymes
15. Type of cell that does not have a true nucleus or membrane-bound organelles
16. Crucial for growth, development, and tissue repair
18. A thread-like structure made up of DNA and proteins that carries genetic information
20. Essential for sexual reproduction and the formation of gametes
22. The diagram is used by biologists to determine the probability of an offspring having a particular genotype
23. A segment of a gene that contains the instructions for making proteins
26. The parent

2. Is the division of the cytoplasm to the two genetically identical cells
4. A specialized subunit within a cell that has a specific function
6. It is made up of nucleotides
7. Having two different alleles for a specific gene
8. This refers to a trait that is influenced by multiple genes
11. A variant form of a gene
12. Can be found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum
17. Are any cell in the body that are not gametes, germ cells, or stem cells
19. Refers to an allele that expresses its trait even when only one copy is present
21. An individual who has one copy of a recessive allele for a genetic trait or condition
24. The DNA in a cell
25. Having two identical alleles for a specific gene
