At the end of meiosis in humans, four gametes are produced that are:   A. Genetically identical to each other and to the parent cell   B. Genetically identical to each other but genetically different from the parent cell   C. Genetically different from each other and the parent cell   D. Genetically identical to the parent cell from different from each other

Gametes contain one of each kind of chromosome because   Select one: A.  The homologous chromosomes separate during meiosis. B.  Crossing-over occurs during prophase I. C.  Only one replication of DNA occurs during meiosis. D.  The chromatids separate during meiosis.

What would happen to the chromosome number in gametes and offspring if ​gametes were formed by the mitotic process instead of the meiotic process?

Draw a diagram of meiosis in a cell where 2n = 6, in a case where there is interchromosomal mixing. Use a clearly labelled colour code (what does each colour represent?) to represent the chromosomes.

Which of the following statements is true? Select one: a. Nondisjunction during anaphase I or anaphase II will have no effect on the gametes formed. b. More gametes will be affected if nondisjunction occurs during anaphase I than if nondisjunction occurs during anaphase II. c. More gametes will be affected if nondisjunction occurs during anaphase II than if nondisjunction occurs during anaphase I. d. Nondisjunction during anaphase I or anaphase II will have the same effect.

An individual can have an abnormal number of chromosomes as a result of nondisjunction. Identify the following example of nondisjunction that results in an abnormal number of chromosomes. A. Sister chromatids do not separate in meiosis II.   B. Homologous chromosomes move apart appropriately during meiosis I.   C. Mitosis occurs normally during embryonic development.   D. Two normal gametes fuse during fertilization.

If an non disjunction occurs in meiosis 2 in a male and the resulting sperm fertilizes a normal female egg, which of the following coujld result. Check ALL that apply a) YO b) XYY c) XXY d) XXX e) XO Polar bodies are formed during Male meiosis Female meiosis Both male and female meiosis Neither male nor female meiosis A brain cell in a normal human male would have a Y chromosome. a) True b) False

Which of the following occur during anaphase II of meiosis?   Select one: a. The APC adds phosphates to motor proteins causing them to rebuild the nuclear envelope. b. Homologous chromosomes of the tetrad separate and move to opposite poles of the newly dividing cell. c. DNA de-condenses. d. Non-identical (due to recombination) sister chromatids are split, attach to motor proteins, and are moved to separate poles
