Across
- 2. One dominant allele and one recessive allele (Tt)
- 3. a genetically determined characteristic
- 7. result of a reproductive process; children
- 8. the material that makes up our chromosomes and stores our genetic information
- 9. allele that masks the presence of another allele for the same gene when they occur together in a heterozygote; shown with capital letters
- 11. one of two or more different versions of the same gene; dominant or recessive
- 12. science of heredity, or how traits are passed from parents to offspring
- 13. Austrian monk who lived in the 1800s and discovered the laws of inheritance by careful, repeated experiments with pea plants; called the “father of genetics”
Down
- 1. a segment of DNA that carries the genetic code to make a specific polypeptide chain
- 2. Two of the same alleles; can be homozygous dominant or homozygous recessive (TT or tt)
- 4. allele that is masked by the presence of another allele for the same gene when they occur together in a heterozygote; shown with lowercase letters
- 5. coiled structure made of DNA and protein that is present during cell division
- 6. characteristics of an organism that depend on how the organism’s genotype is expressed; {the effect of the code}
- 10. a way to describe the combination of alleles that an individual has for a certain gene; usually letter combinations (TT, tt, Tt) {the code}
