- 3. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
- 6. is a self-replicating material
- 8. having two different alleles of a particular gene or genes.
- 11. is a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
- 12. a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores
- 13. investigate the genetic constitution of (an individual organism).
- 14. is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Down
- 1. relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents
- 2. is a measurement tool that helps us predict the chances of an offspring being inherited with a particular trait of interest.
- 4. a distinguishing quality or characteristic
- 5. having two identical alleles of a particular gene or genes.
- 7. a square diagram that is composed of a grid of usually four boxes and is used to calculate and depict all the combinations and frequencies of the different genotypes and phenotypes among the offspring
- 9. a distinct sequence of nucleotides forming part of a chromosome
- 10. relating to or denoting heritable characteristics which are controlled by genes that are expressed in offspring even when inherited from only one parent.
