Across
- 4. produced by similar alleles
- 9. Of germ cells, possessing half (23 chromosomes in humans) the diploid number of chromosomes found in somatic cells
- 10. In genetics, pert. to a trait or characteristic that is expressed only if present in the genes received from both parents
- 11. Possessing different alleles at a given locus
- 12. the expression of the genes present in an individual
- 13. basic unit of heredity, made of DNA, the code for a specific protein.
Down
- 1. A photomicrograph of the chromosomes of a single cell, taken during metaphase, when each chromosome is still a pair of chromatids.
- 2. Any of two or more different genes containing specific inheritable characteristics that occupy corresponding loci on paired chromosomes
- 3. In genetics, pert. to a trait or characteristic that is expressed in the offspring although it is carried on only one of the homologous chromosomes
- 5. female germ cell
- 6. A process of two successive cell divisions, producing cells, egg or sperm, that contain half the number of chromosomes (haploid) in somatic cells
- 7. the pair of genes present for a particular characteristic or protein
- 8. is a linear strand made of DNA that carries genetic information.
