Question
The difference between mitosis and meiosis is A. Crossing over occurs in mitosis but not meiosis B. in mitosis, homologous pairs of chromosomes line up at the metaphase plate C. in meiosis, sister chromatids exchange genetic information with one another D. in meiosis. homologous pairs of chromosomes will independently assort and the offspring will get different combinations of Mom and Dad s genes If a cell has 6 chromosomes from Mom and 6 chromosomes from Dad: A. it would be diploid and 2n = 12 B. it could be haploid or diploid C. it would be haploid with n = 6 D. If the cell underwent meiosis, the resulting daughter cell would have 12 chromosomes A. Sister chromatids exchange genetic material to increase diversity during meiosis B. Sister chromatids separate at mitosis but non-sister chromatids always stay together C. Sister chromatids should have the same DNA sequence as one another but non-sister chromatids will have differences in their DNA sequences. D. Non-sister chromatids and sister chromatids are the same, but just have different names depending on the cell type.Explanation / Answer
Answer:
6). D). In meiosis, homologous pairs of chromosomes will independently assort and the offspring will get different combination of Mom and Dad’s genes.
Crossing over & pairing of homologous chromosomes (synapsis) occurs in meiosis. And there will be no exchange of genetic material between in meiosis.
7). A). It would be diploid and 2n = 12
Each diploid cell obtains half of its chromosomes from the mother and remaining half of the chromosomes from the father.
Diploid= 2n = 12
haploid = n = 6
8). C). Sister chromatids should have the same DNA sequence as one another but non-sister chromatids will have differences in their DNA sequences.
Two chromatids of a chromosome are called sister chromatids. They would not have difference in gentic make up and they not exchange genetic material.
A chromatid of one chromosome and a chromatid of its homologous chromosomes are called non-sister chromatids. They have different genetic make up and genetic material exchange occurs between the non-sister chromatids of the homologous chromosomes.
