genetics
Across
- 2. the process of making genes into proteins
- 5. matched pairs of chromosomes
- 7. expression process of putting dna codes to use
- 13. the division of the cell cytoplasm, usually follows mitosis
- 15. requires two parents
- 18. physical expression of traits
- 19. Cells reproductive cells in the testes
- 20. the four reproductive cells produced by meiosis type of cell division necessary for sexual reproduction
- 22. used to translate code from the dna
- 24. when the chromosomes attached at the center, or centromeres line up on the spindle at the center of the cell
- 26. combination of alleles inherited from the parents
- 27. a change in a gene, structure, or a combination of genes
- 29. the entire collection of alleles of genotypes
- 30. reproductive cells in the ovaries
- 31. chromatin again forms from the chromosomes and a cell membrane begins to grow across the center between the two nuclei
- 33. alternate forms of genes
- 34. differentiation cells take on their unique structure as part of the team of the body
- 35. inherits two of the same alleles for a particular trait either both dominant or both recessive
- 36. when the expression of genes can be turned on or off
Down
- 1. used to express the possible combinations for a certain trait an offspring may inherit
- 2. when the nucleus of the cell organizes the chromatin material into structures called chromosome
- 3. carries dna
- 4. cells all cells of the body except for reproductive cells
- 6. when both traits appear in the F1 generation and contribute to the phenotype of the offspring
- 8. the resting period before meiosis II begins
- 9. the passing of traits from a parent to offspring
- 10. when one allele is stronger than the other
- 11. when one trait is not complete over the other
- 12. the processes of mitosis and cytokinesis
- 14. genetic basis of life
- 16. the weaker gene
- 17. genes genes that direct body plan development
- 21. reproduction results in offspring that are identical to the single parent cell
- 23. involves getting rid of mutated gene, fixing the mutated gene, or replacing the mutated gene
- 24. the name for the process of asexual reproduction
- 25. study of traits passed from generation to generation
- 28. chromosomes separate at the center and the spindle pulls them toward either end of the cell
- 29. specific portions of DNA
- 32. inherits one dominant allele and one recessive allele
