Across
- 2. genes located on the X or Y chromosome such as colorblindness or hemophilia
- 3. A pattern of inheritance in which there are more than two possible alleles
- 4. principle that states that genes for different traits can segregate independently of each other during meiosis if they are on different chromosomes
- 6. trait that lies on human chromosomes 1 through 22
- 10. type of trait that requires the presence of two alleles in order to show the trait (like blue eyes)
- 11. this principle states that the presence of even one allele means the individual will always show that characteristic
- 17. type of inheritance in which the heterozygous phenotype is a mix of the two homozygous phenotypes
- 18. visual representation of the complete diploid set of human chromosomes grouped together in pairs arranged in order of decreasing size used to look for genetic disorders
- 19. different forms of the same gene
- 20. combination of alleles or genetic makeup for an organism
Down
- 1. used to predict the probability of genotypic and phenotypic combinations in genetic crosses
- 5. during gamete formation, the alleles for each gene separate from each other so each gamete only carries one allele for each gene
- 7. genotype containing two different alleles
- 8. type of inheritance in which the heterozygous phenotype completely expresses both alleles
- 9. genotype containing two identical alleles
- 12. chart that shows the pattern of inheritance of a particular trait within a family over multiple generations
- 13. physical traits or characteristics of an organism
- 14. Austrian monk who used peas to establish the basic principles of genetic inheritance
- 15. trait in which more than one gene contributes to the phenotype
- 16. section of a chromosome that codes for a protein
