  1. 3. a genotype with two different alleles of a given gene or locus
  2. 6. The genetic makeup of an individual; the allele(s) possessed at a given locus
  3. 8. feature of an organism
  4. 10. A specific location on a chromosome
  5. 13. the alleles of two more genes get sorted into gametes independent of each other.
  6. 14. A phenotype or allele exhibited only when homozygous
  7. 15. a genotype with two dominant alleles of a given gene or locus

  1. 1. During the formation of gamete, each gene separates from each other so that each gamete carries only one allele for each gene.
  2. 2. A linear or circular strand composed of DNA that contains genes
  3. 4. a genotype with two recessive alleles of a given gene or locus
  4. 5. when there are two alleles of a gene, the dominant allele is always expressed because it masks the recessive allele.
  5. 7. A phenotype or allele that completely masks the presence of the other, recessive allele in the heterozygote
  6. 9. The physical characteristics of an individual
  7. 11. Alternative forms of a gene
  8. 12. The fundamental unit of heredity; a specific section of DNA within a chromosome
