- 5. Deoxyribonucleic acid. A molecule that contains the instructions an organism needs to develop, live and reproduce.
- 7. An allele or a gene that is expressed in an organism's phenotype, masking the effect of the recessive allele or gene when present.
- 9. A diploid organism with two alleles, each of a different type.
- 10. Offspring resulting from a true breeding.
- 12. The expression of a particular trait, for example, skin color, height, behavior, etc., according to the individual's genetic makeup and environment.
- 13. The likelihood of an event to occur.
- 17. A diagram that is used to predict the genotypes of a particular cross or breeding experiment.
- 18. A form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive.
- 19. Responsible for the physical and heritable characteristics or phenotype of an organism.
- 21. Simon Says answer
Down
- 1. A diploid organism with two alleles, each identical for a single trait.
- 2. The study of heredity, or how the characteristics of living things are transmitted from one generation to the next.
- 3. Any genetically determined characteristic.
- 4. the set of genes in our DNA which is responsible for a particular trait.
- 6. A form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
- 8. The result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera.
- 11. Ribonucleic acid. A nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
- 14. A set of three adjacent nucleotides, also called triplet.
- 15. Adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing.
- 16. A gene that can be masked by a dominant gene.
- 20. One of the possible forms of a gene.
