- 2. Expression of two opposing alleles in a heterozygote, resulting in a phenotype that is hybrid.
- 4. When three or more alleles occur at a site or locus.
- 6. The size, banding patterns, and centromere position of an individual's chromosomes, as well as their number and appearance.
- 9. Alleles that are involved in the majority of visible characteristics.
- 11. Postulates developed by Mendel regarding genetics.
- 13. Process where two haploid cells are produced by the parent cells and are fused to form a single, genetically recombined diploid cell.
- 16. The trait which confers the same physical appearance.
- 17. Trait that is not expressed when the dominant trait is present.
- 18. It implies that more than one factor, whether genetic, environmental, or both, is involved in the phenotype's origin.
- 21. Mutation-induced gene variants that occur at the same relative sites on homologous chromosomes.
- 25. It is a structure in the nucleus that includes chromatin, which contains DNA, the genetic material.
- 27. Multiple, seemingly unconnected phenotypic consequences caused by genes or mutations.
- 28. Location
- 29. It suggests that only genetic components are involved, generally additively, with the original definition implying that the number of factors (loci) is too big to be separately defined.
- 31. A period of the cell cycle when the duplicated chromosomes are separated into identical nuclei; includes prophase, prometaphase, metaphase, anaphase, and telophase.
- 32. An organism's inherited genetic basis, which includes both physically expressed and non-expressed alleles.
- 34. Observable characteristics of an organism reflected from the genotype
- 36. Antagonistic gene interaction in which one gene suppresses or interferes with the expression of another.
- 37. Basic unit of heredity and unique DNA segment that codes for a functioning molecule.
- 38. Analysis used to study the pattern in human inheritance.
- 39. Two different alleles are present in a genotype.
- 40. Other term for 'multiallelic'
Down
- 1. Change or variation in the nucleotide sequence of a genome.
- 3. Set of genotypes with the same phenotype.
- 5. The chromosomes' building material
- 7. Changes in chromosome structure or number
- 8. The percentage of the time that a dominant or homozygous recessive gene or gene combination reveals itself in the carriers' phenotypic.
- 10. Location of a gene in a chromosome.
- 12. Stages or steps in cell division.
- 13. Means segregation at a single locus.
- 14. Term used to describe features that do not show clear one-locus ("Mendelian") segregation, frequently due to segregation at many loci.
- 15. When two alleles occur at a site or locus.
- 19. Similar alleles are present in a genotype.
- 20. When only one allele occurs at a site or locus.
- 22. A natural chromosomal or DNA variation. If a rare allele has a frequency of 1% or greater, a gene locus is said to be __________.
- 23. Inheritance patterns that do not follow Mendelian principles.
- 24. Expression of both alleles for the same trait in their whole and at the same time in heterozygous individuals.
- 26. A set of alleles that are inherited together from closely related gene loci.
- 30. Two or more alleles.
- 33. The direct uptake and integration of external genetic material from its surroundings across the cell membrane causes a genetic change in a cell.
- 35. Occurence of only one allele in a trait, as in X-linkage.
