6. epistasis

  • the interaction between two genes when one allele affects the expression of another which can lead to a graduation of a phenotype
  • a cell with one copy of a gene
  • when two dominant alleles in an heterozygous individual occurs and intermediate phenotype occurs
  • a cell with two copies of a gene

7. what is the definition of a gene

  • different forms of the same gene.
  • the genetic constitution of an organism
  • the section of DNA which codes for a protein. The sequence of bases in the DNA determines the sequence of amino acids in the protein.
  • the expression of its genetic constitution and its interaction with the environment

8. what is the definition of recessive alleles

  • two copies of the gene are different alleles
  • this allele will only be express in the phenotype if the genotype is heterozygous ozygous
  • this allele will only be express in the phenotype if the genotype is homozygous
  • different forms of the same gene

9. what is the definition of a haploid cell

  • a cell with one copy of a gene
  • a cell with two copies of a gene
  • this allele will only be express in the phenotype if the genotype is homozygous

10. what does codominance mean

  • a cell with one copy of a gene
  • the interaction between two genes when one allele affects the expression of another which can lead to a graduation of a phenotype
  • when two dominant alleles in an heterozygous individual occurs and intermediate phenotype occurs
  • a cell with two copies of a gene

11. what is the definition of alleles

  • different forms of the same gene
  • the genetic constitution of an organism
  • the expression of its genetic constitution and its interaction with the environmen
  • the section of DNA which codes for a protein. The sequence of bases in the DNA determines the sequence of amino acids in the protein.

12. what is the definition of homozygous

  • two copies of the gene are different alleles
  • different forms of the same gene
  • two copies of the gene are the same allele
  • the section of DNA which codes for a protein. The sequence of bases in the DNA determines the sequence of amino acids in the protein.

13. what is the definition of phenotype

  • two copies of the gene are the same allele
  • different forms of the same gene
  • the expression of its genetic constitution and its interaction with the environment
  • the genetic constitution of an organism
