Across
- 2. describes cells that have only one set of chromosomes
- 5. Cells used during sexual reproduction to produce a new individual organism or zygote - contain half the number of chromosomes of regular body cells.
- 6. term is used when an individual has two identical alleles for a gene
- 7. the cell that forms by the merging of an egg and a sperm during fertilization. It contains a full set of chromosomes, half from each parent, making it diploid.
- 9. refers to the genetic makeup of an individual, or what alleles they have.
- 11. different versions of the same gene.
- 12. the visible or observable expression of the genotype
- 14. cells that have two sets of chromosomes, one from each parent
- 15. All the cells in the body except for the gametes and the cells that make gametes - they have a full set of chromosomes.
Down
- 1. an allele that can determine a trait on its own, regardless of the other allele.
- 3. the study of genes and how traits are inherited from parents to offspring. It explores how the information encoded in genes can lead to different traits in organisms.
- 4. describes having two different alleles for a gene
- 8. masked by a dominant allele and only shows its effect if the individual has two copies
- 10. a chart that geneticists use to predict the possible genotypes of offspring in a genetic cross - helps to visualize how alleles from each parent can combine and what traits might result
- 13. characteristics or features of an organism, such as hair color, eye color, or height, which can be inherited from parents.
