Questions and Answers

What is a recessive gene?

  • A gene that cannot be covered up
  • A gene that is always passed down from the parents to the offspring
  • A gene that always expresses itself in an individual's phenotype
  • A gene that can be hidden by the dominant version (correct)

    • What do alleles refer to?

  • Two copies of a gene, which can be slightly different from each other (correct)
  • The physical characteristics of an organism
  • The protein expression in an individual
  • The variations in DNA sequence

    • When does a recessive allele produce a recessive phenotype?

  • When the individual has one copy of the dominant allele
  • When the individual has no copies of the dominant allele
  • When the individual has two copies of the recessive allele (correct)
  • When the individual has one copy of the recessive allele

    • What does a dominant allele produce in individuals who have one copy of the allele?

    Study Notes

    Genes and Alleles

    • A recessive gene is a type of gene that will only be expressed if an individual has two copies of the gene, one from each parent.
    • Alleles refer to different forms of a gene that occupy the same position on a chromosome.
    • A recessive allele produces a recessive phenotype when an individual has two copies of the allele, one from each parent.

    Dominant Alleles

    • A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, inherited from either parent.

    Gene Function

    • The function of genes in an organism's DNA is to provide instructions for the development and function of an organism.
    • Genes are responsible for creating proteins, which are essential for various cellular functions and processes.

    Dominant Genes

    • A dominant gene is a gene that will be expressed if an individual has one copy of the gene, inherited from either parent.

    Impact of Variations

    • Variations in protein activity or expression can have a significant impact on an organism's traits, resulting in changes to its physical characteristics, behavior, or susceptibility to diseases.
