Mendel's Law of Independent Assortment states that:
the members of a pair of homologous chromosemes assort independently of each other during gamete formation
none of these
the members of a pair of homologous chromosomes separate from each other during gamete formati
different pairs of homologous chromosomes assort independently of each other during gamete formation
different pairs of homologous chromosomes separate from each other during gamete formation
The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose.
Human individuals with XXY (an additional X chromosome) are male. Individuals with XO (only one X chromosome) are female. For the following family, identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the child.
A man with a pointed nose and a woman with a round nose have a daughter with a round nose. This daughter has Turner Syndrome (genotype XO: one X chromosome).
Nondisjunction must have occurred in melosis 2 of the mother
More than one of the answers is correct
Nondisjunction must have occurred in meiosis 1 of the father
Nondisjunction must have occurred in meiosis 1 of the mother
Nondisjunction must have occurred in meiosis 2 of the father
A color-blind woman with Turner syndrome (XO) has a father who is color blind.Given that the gene for the color-blind condition is recessive and X-linked, provide a likely explanation for the origin of the color-blind and chromosome constitution in the color-blind woman.
nondisjunction in the mother in meiosis I or II
nondisjunction in the father at meiosis I
no abnormalities had to occur to produce this daughter
nondisjunction in the father in meiosis I or II
nondisjunction in both the mother and father in meiosis I.
