Genetics
Across
- 4. dominance is when there is no dominant or recessive trait
- 7. are structures found in the center (nucleus) of cells that carry long DNA Fragments
- 9. polygenic trait is a characteristic that is influenced by two or more genes
- 11. compare
- 12. problems are those of an inherited medical condition caused by an abnormality in the DNA.
- 14. crosses are two observed traits that are controlled by two different genes
- 16. is when a person cannot produce melanin, which is the substance that gives color to hair, skin, and the iris of the eyes, and therefore has no pigmentation.
- 17. is the physical characteristics of something living, especially those characteristics that can be
- 18. nucleus is a membrane-bound organelle containing the cell chromosomes
Down
- 1. is the scheme that explains the traits and genes that are transmitted in a family.
- 2. segment containing DNA carrying information that determines our traits
- 3. occurs when a single gene affects many traits.
- 5. monohybrid cross is a process of mating between two individuals with dominant genotypes
- 6. is when a person has more than 5 fingers on each hand or 5 toes on each foot.
- 8. is People who usually have short arms and legs, a larger than normal head, and a medium-sized trunk.
- 10. is the Presence of two different alleles at a given gene locus
- 13. is an inheritance pattern where both alleles in heterozygous offspring are completely dominant
- 15. is one of two or more DNA sequences occurring at a particular gene locus
