.🧬🧬🧬
Those terms which are mostly used in genetic subject.
🧬1. -🔬
the condition of having only one set of chromosomes per cell .
🧬2. -🔬
the condition of having two sets of chromosomes per cell (2n)
🧬3. - 🔬
a haploid s*x cell in plants and animals (egg or s***m)
🧬4. -🔬
diploid (2n) cell resulting from the union of two gametes in s*xual reproduction
🧬5. - 🔬
the complex of DNA, RNA and proteins that makes up uncondensed eukaryotic chromosomes.
🧬6. -🔬
structures within the nucleus of eukaryotic cells composed of chromatin and visible at cell division (condensed chromatin).
🧬7. 🔬 -chromosomes that are similar in morphology (shape and form) and genetic constitution. In animals one set comes from the father and the other from the mother.
🧬8. -🔬
one of the two halves of a duplicated chromosome
🧬9. - 🔬
specialized constricted region of a chromatid, that contains the kinetochore; sister chromatids are joined at the centromere during cell division
🧬10. -🔬
exchange of genetic material between chromosomes
🧬11. -🔬
the breaking and rejoining of homologous (non-sister) chromatids during early prophase I of meiosis, resulting in recombination
🧬12. -🔬
the pairing of homologous chromosomes during prophase I of meiosis.
🧬13. - 🔬
separation of homologous chromosomes (or sister chromatids) during anaphase.
🧬14. -🔬
the genetic make-up (the assemblage of alleles) of an individual.
🧬15. - 🔬
the physical or chemical expression of an organisms genes.
🧬16. - 🔬
a discrete unit of hereditary information that usually specifies a protein; a region of DNA (locus) located on a chromosome that specifies a trait (characteristic).
🧬17. -🔬
genes governing variations of the same characteristic (trait) that occupy corresponding positions (loci) on homologous chromosomes; alternative forms of a gene.
🧬18. - 🔬
an allele that is always expressed when present.
