Answer:
Functionalism
Explanation:
Functionalism is the theoretical perspective in sociology, posits that for stability and social order to be established in a society, all social institutions that make up the society, must work interdependently to contribute to the functionality of the society. Social institutions in a society include, the government, family, economy, religion, media,education.
For example, for most societies that seem relatively stable, the family pay taxes to the government, the government as an institution rely on these taxes to provide education for the children of the family in that society. All parts of this society are interdependently inherently connected.
Answer:
At meiosis II in the mother
Explanation:
Both the parents have normal vision but both the sons are colorblind. Since colorblindness is X linked recessive disorder, the sons have obtained the allele for colorblindness from mother. This makes the mother carrier for colorblindness. The genotype of the mother is X^cX. The young man with Klinefelter syndrome is colorblind which means that he is homozygous recessive for the allele of colorblindness. His genotype is X^cX^cY. Since this man has obtained two copies of the allele of colorblindness, the mother must have experienced nondisjunction at meiosis II during gamete formation.
Anaphase-II of meiosis II separates and segregates the sister chromatids (now called daughter chromosomes) to opposite poles. Failure of segregation of two copies of X^c chromosome of mother to opposite poles and their distribution to the same egg cell resulted in the formation of an egg with two copies of X^c chromosome. Fertilization of this egg with a sperm carrying "Y" chromosome as sex chromosome resulted in a zygote with X^cX^cY that developed into the man with Klinefelter syndrome and colorblindness.
