Genetics Review
Practice Question What inference can be made from the diagram shown? A. The sperm will have double the amount of chromosomes as the parent cell. B. None of the cells made copies of their chromosomes C. The sperm will have half the number of chromosomes as the parent cell.
The diagram above shows the process of meiosis The diagram above shows the process of meiosis. The segregation that occurs during meiosis results in a — A decrease in the total number of cells per organism B reduction in the number of chromosomes per cell C group of genetically identical cells
Compare to mitosis, Meiosis will result in A. 2 Daughter cells B. 4 Daughter Cells C. Less number of daughter cells than mitosis
What is the name of this process? Mitosis DNA replication Crossing over
Which of the following is NOT a result of Crossing over? Both chromosomes with identical genes New combination of genes in each chromosome Genetic variability
Which process of Meiosis is represented by “X”? Mitosis Meiosis I Meiosis II
