Q1: Throughout ____, the nuclear envelope disappears, and the chromosomes become different.
A. Telophase
B. Anaphase
C. Metaphase
D. Prophase
E. Interphase
Q2. Crossing-over takes place during:
A. Metaphase I.
B. Metaphase II.
C. Prophase I.
D. Prophase II.
E. Anaphase I.
Q3. In organisms which are parthenogenetic, females produce young which are female without any fertilization of eggs occurring? Name the process which could theoretically accomplish this via modification of the normal meiotic cycle?
A. A haploid egg develops into a female; females just complete meiosis I.
B. A polar body fuses with egg nucleus in place of the sperm and females complete meiosis.
C. Meiosis stops before anaphase, telophase or cytokinesis takes place, leaving a full diploid individual.
D. All of the above would theoretically make parthenogenesis if the offspring was viable.
Q4. What do you mean by alleles?
A. Genes for various traits, like hair color versus eye color.
B. Alternative forms of a gene for a specific trait, like blue eyes or brown eyes.
C. The locations of genes on a chromosome.
D. Recessive forms of a type of characteristic taken by genes.
E. Dominant forms of a type of characteristic taken by genes.
Q5. For Mendel's law of segregation to take place, the alleles should be:
A. At different loci on similar chromosome.
B. On a homologous pair of chromosomes.
C. On a non-homologous pair of chromosomes.
D. At similar loci on the similar chromosome.
