During meiosis, homologous chromosomes synapse and form tetrads. In a homologous pair, one of the chromosomes comes from the mother (maternal homologue) and one comes from the father (paternal homologue).Since replication occurs before meiosis, each tetrad consists of four chromatids (tetra means four). The chromatids of the same homologue are called sister chromatids, and the chromatids of different homologues are called non-sister chromatids.If the maternal homologue carries allele A and the paternal homologue carries allele a for a certain gene, which of the following will have different alleles for this gene?
Select one:
a. Non-sister chromatids
b. Sister chromatids
c. None of the chromatids, since each chromatid in a tetrad contains the same allele
d. All four chromatids, since each chromatid in a tetrad has a different allele
 
Germ cells are specialized cells that develop into gametes. Gametes are produced through the process of meiosis.If the diploid number for humans is 46 chromosomes, how many chromatids does a cell undergoing meiosis have at each of the following phases?Select the row that correctly shows the number of chromatids at each phase.
Select one:
a. G2 of Interphase Metaphase I Prophase II 92 92 46
b. G2 of Interphase Metaphase I Prophase II 46 92 23
c. G2 of Interphase Metaphase I Prophase II 92 46 46
d. G2 of Interphase Metaphase I Prophase II 46 46 23

The diploid chromosome number of a cat, Felis catus, is .Which of the following rows correctly identifies the number of egg cells and chromosomes in each cell after the process of oogenesis has completed?
Select one:
a. # of Cells # of Chromosomes
b. # of Cells # of Chromosomes  
c. # of Cells # of Chromosomes
d. # of Cells # of Chromosomes  

  

Use the following information to answer the next two questions.Nondisjunction is an error in meiosis that results in non-separation of chromosomes during anaphase. Nondisjunction can occur during anaphase I or anaphase II of meiosis.

Which of the following correctly describes the gametes that will form as a result of nondisjunction during anaphase II in a human male?
Select one:
a. Four sperm with  chromosomes
b. Two sperm with  chromosomes, one sperm with  chromosomes, and one sperm with  chromosomes
c. Two sperm with  chromosomes and two sperm with  chromosomes
d. Four sperm with  chromosomes
 
Which of the following statements is true?
Select one:
a. More gametes will be affected if nondisjunction occurs during anaphase I than if nondisjunction occurs during anaphase II.
b. Nondisjunction during anaphase I or anaphase II will have the same effect.
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 no effect on the gametes formed.
 
Which of the following cells is penetrated by a sperm cell during the process of fertilization?
Select one:
a. Secondary oocyte
b. Oogonia
c. Primary oocyte
d. Ovum
