    Cards (22)

    • What is the focus of today's video?
      Different genetic terms and concepts
    • What is an allele?
      A different version of the same gene
    • What is the difference between dominant and recessive alleles?
      Dominant alleles are expressed over recessive ones
    • What does homozygous mean?
      Having two identical alleles for a gene
    • What does heterozygous mean?
      Having two different alleles for a gene
    • What is a gene?
      A segment of DNA coding for a protein
    • How do genes determine characteristics?
      They code for proteins that influence traits
    • How are most characteristics determined?
      By several interacting genes
    • What is the significance of alleles?
      They are different forms of the same gene
    • What happens if a mouse is heterozygous for fur color?
      One allele will be dominant, expressed
    • What color will a heterozygous mouse be if the purple allele is dominant?
      The mouse will be purple
    • What is required for a mouse to be green?
      Both alleles must be for green fur
    • What does homozygous recessive mean?
      Having two alleles for green fur
    • What is the genotype?
      The entire collection of alleles
    • How do different genotypes affect phenotype?
      Different genotypes can lead to different phenotypes
    • What is the phenotype?
      The observable characteristics from genotype
    • How can two mice have the same phenotype but different genotypes?
      They can have different alleles but show the same trait
    • What is the phenotype of a homozygous recessive mouse?
      The mouse will be green
    • What are the key terms related to genetics discussed in the video?
      • Allele
      • Dominant
      • Recessive
      • Homozygous
      • Heterozygous
      • Genotype
      • Phenotype
    • How do genotype and phenotype differ?
      • Genotype: Collection of alleles
      • Phenotype: Observable characteristics from genotype
    • What is the relationship between genes and proteins?
      • Genes code for specific proteins
      • Different alleles can code for different protein forms
    • How do multiple genes influence traits like height?
      • Several genes interact to determine height
      • Each gene contributes to the overall trait
