Question
What aspect of chromosome behavior most clearly accounts for Mendel's Principle of Segregation?
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
2. What aspect of chromosome behavior most clearly accounts for Mendel's Principle of Independent Assortment?
A. Movement of sister chromatids to opposite poles at anaphase II of meiosis.
B. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis.
C. Crossing over between homologous chromosomes during prophase I of meiosis.
D. Replication of chromosomes prior to meiosis.
E. Independent alignment of different homologous pairs on the metaphase I spindle.
6) Me2CuLi, then H30+ 7) CO2, then H20 8) DIBAL, then H20 (H- 1 equiv) 9) NaN3; then LiAIH4 excess 10 NExplanation / Answer
1.B.movement of homologous chromosome to opposite pole at anaphase 1 of meiosis
Note- this is when the pair of homologous chromosome seggregate into different cell,also with this the homologous gene or allele would seggregate on these chromosome.
2.E.independent alignment of different homologous pair on metaphase 1 spindle.
Note- this is when the homologous chromosome assort independently from each other and seprate into different cell.
