  • What does homozygous mean?
    two copies of gene versions that are create another gene
    two copies of gene versions that are the same
    two copies of gene versions that are mutated
    two copies of gene versions that are different
  • Which part of the cell builds the proteins that determine an organisms traits?
    Nucleus
    Ribosomes
    Proteins
    Gland
  • Which part of the cell below shows a NUCLEUS?
    Tan
    Pink
    Black
    Blue
  • Horse 1 has two different copies of a gene for tongue color, but Horse 2 has the same copies of a gene for tongue color.
    So Horse 1 will have 1 type of proteins, but Horse 2 will have 2.
    It is impossible to say anything about their proteins
    So Horse 1 will have 2 types of proteins, but Horse 2 will have 1.
    So Horse 1 will have 2 types of proteins and Horse 2 will have 2 types.
  • Which part of the cell below shows a GENE VERSION (ALLELE)?
    Tan
    Black
    Pink
    Blue
  • Why do siblings and parents different from each other?
    Siblings use their environment to determine traits
    Siblings have a mutation that causes them to be different
    Siblings get different amounts of genes from their parents
    Siblings inherit different combinations of gene versions from parents
  • Three bunnies have different parents but all have the same proteins for their fur color. What can we say about the fur?
    They will have different fur colors b/c the genes will connect the same
    There is no way to tell what their fur color will be
    They will have the same fur color b/c the proteins will connect the same
    They will have different fur colors b/c the proteins will not connect
  • Two beetles have different parents. One has red wings while the other has white wings. Why do they have different wings?
    The different gene versions connect in different ways
    The parents were different, so the wings will be different
    The different gene versions instruct for different proteins
    The different gene versions mean the genes are different colors
  • What do you call a random change to a gene that can 'sometimes' result in a new trait?
    heterozygous
    mutation
    homozygous
    variation
  • Otis and Ruby had an offspring with a color mutation. Which statement must be true?
    The offspring will have extra long legs
    The offspring will have more fur bristles
    The spider will have nothing unusual
    The offspring's genes have some sort of change
  • A spider has brown skin. Its mother had yellow and its father had brown. Which explains why the spider has brown skin?
    It inherited one from each parent and the genes connected together
    It inherited one from each parent and the genes instructed for proteins
    It inherited one copy from dad and none from mom
    It inherited one copy from mom and none from dad
  • Below is a picture of a silk gland cell. There are TWO different proteins being made. This cell is....
    heterozygous
    homozygous
  • Why are humans doing so much research on spider silks?
    They want to create a super spider with the best silk
    They would like to use spider silk for fishing equipment
    They would like to create their own spider silks to catch prey
    They want to create medical supplies like stitches and artificial tendons
  • Which part of this cell gives instructions for what proteins should be built?
    Ribosome
    Nucleus
    Venom
    Silk Gland
  • Which part of the cell below shows a PROTEIN?
    Pink
    Blue
    Tan
    Black
  • Which part of the cell below shows a RIBOSOME?
    Blue
    Pink
    Black
    Tan
  • If the structure of a kangaroo's fur proteins changed, but the amount of that protein stays the same, what will happen?
    The changed protein interacts differently, but the function is the same
    The amount of that protein stayed the same so the function won't change
    The changed protein will interact the same way but the function will change
    The changed protein interacts different, so the function will change
  • How does sexual reproduction result in a variation among offspring?
    An organism has two copies of a gene for each feature
    Each parent randomly passes on one of it's two copies of genes
    Proteins interact with other proteins
    Traits are different between parents, offspring and siblings
