    Determine the sex for the organism

  • Question 4
    20 seconds
    Q.

    An allele is

    answer choices

    A version of a gene

    Another word for a gene

  • Question 5
    30 seconds
    Q.

    Which of the following is TRUE?

    answer choices

    Sex chromosomes determine gender

    Males have XY; Females have XX

    all of these

  • Question 6
    30 seconds

    phenotypes

    genotypes

  • Question 11
    30 seconds
    Q. Autosomes are
    answer choices
    chromosomes found in autotrophs, only
    chromosomes that automatically correct all errors in the DNA
    chromosomes that determine traits other than sex
    chromosomes that determine the sex of the individual
  • Question 12
    30 seconds
    Q.

    The sex of a child is determined by

    answer choices

    whether the father's sperm contains an X or Y chromosome

    whether the mother's egg contains an X or Y chromosome

    the age of the parents

    none of these are correct

  • Question 13
    30 seconds
    Q. Why is the gene for a disease or disorder more likely to be found on the X chromosome than Y?
    answer choices
    The X chromosome has many more genes
    The Y chromosome has many more genes
  • Question 14
    30 seconds
    Q. Males are more likely to suffer from a sex-linked disease or disorder because
    answer choices
    males are the weaker sex
    males have less DNA
    males have 1 X chromosome, so the disorder is more likely to be expressed
  • Question 15
    30 seconds
    Q.

    Why are men 16 times more likely to be color-blind than women?

    answer choices

    to be color-blind, you must have a Y chromosome

    Females must get TWO recessive genes for the trait where as males only need ONE of the recessive genes

    color-blindness is caused by testosterone

    color-blindness is caused by the same gene as baldness
