  1. 3. Inheritance that produce a heterozygote with a phenotype that is intermediate or in between the phenotypes of the homozygote parent
  2. 4. allele that is masked by the presence of a dominant allele and can only appear phenotypically if homozygous.
  3. 7. number of chromosomes in the cell (46n)
  4. 8. Genetic make up of an organismPhenotype - Physical appearance of an organism
  5. 11. is the pattern of inheritance in individuals that have two different alleles for a certain gene, one allele is dominant and the other is recessive.
  6. 12. is a section of DNA that contains the information for a particular genetic characteristics.
  7. 16. are thread-like structure that are made up of a long molecule of DNA
  8. 17. is the ability of one parent to pass its genetic characteristics onto their offspring
  9. 18. is the study of heredity or how characteristics are passed from parents to offspring.
  10. 20. Inheritance refers to two or more genes that have influence on the phenotype of an organisms
  11. 21. is a type of cell division that forms four haploid cells
  12. 22. is the reappearance of an ancestral characteristics after it has apparently not come to light for few generation
  13. 24. Occurs when the contribution of both alleles are visible in phenotype
Down
  1. 1. different form of the same gene
  2. 2. condition in which one allele of a gene is dominant over the other (recessive) such that only the dominant allele influence the phenotype in the heterozygous condition
  3. 5. a genetic cross between parents that have different alleles for one particular gene
  4. 6. half the number of chromosomes in the cell (23n)
  5. 8. characteristics that are passed from parent to offspring.
  6. 9. alleles is a mechanisms of inheritence that involves more than two alleles for one genes
  7. 10. individual has different alleles for a particular gene
  8. 13. cross genetic cross between parents that differ in two characteristics controlled by two genes
  9. 14. Individual has the same alleles for a particular gene on both chromosomes.
  10. 15. is the transfer of characteristics(such as height, colour)from parent to their offspring
  11. 19. Inheritance in which the expression of one gene is controlled by the another gene
  12. 23. position of a gene on a chromosome.
