  1. 3. 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.
  2. 5. Adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing.
  3. 9. A diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next
  4. 11. Responsible for the physical and heritable characteristics or phenotype of an organism.
  5. 12. A form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
  6. 14. Deoxyribonucleic acid. A molecule that contains the instructions an organism needs to develop, live and reproduce.
  7. 16. The study of heredity, or how the characteristics of living things are transmitted from one generation to the next.
  8. 17. the set of genes in our DNA which is responsible for a particular trait.
  9. 20. A diploid organism with two alleles, each identical for a single trait.
  10. 21. The result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera.
  11. 22. One of the possible forms of a gene.
Down
  1. 1. Offspring resulting from a true breeding.
  2. 2. The likelihood of an event to occur.
  3. 4. 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.
  4. 6. The expression of a particular trait, for example, skin color, height, behavior, etc., according to the individual's genetic makeup and environment.
  5. 7. A diploid organism with two alleles, each of a different type.
  6. 8. Any genetically determined characteristic.
  7. 10. A gene that can be masked by a dominant gene.
  8. 13. A diagram that is used to predict the genotypes of a particular cross or breeding experiment.
  9. 15. A set of three adjacent nucleotides, also called triplet.
  10. 18. Simon Says answer
  11. 19. An allele or a gene that is expressed in an organism's phenotype, masking the effect of the recessive allele or gene when present.
