Somatic vs Gametic Mutations

Gene Expression - How different types of cells are formed, how specialized cells are formed

1

Match the following to their correct definitions

Draggable emne		Korresponderende emne
Chromosome reduction		The process during meiosis results in the random distribution of chromosomes to gametes.
Independent assortment		The process that lead to genetic diversity and it ensures the survival of a species.
Crossing over		The process which the chromosome number is reduced to ensure that each child receives a complete set of chromosomes.

Identify whether the following statements belong to Meiosis I or Meiosis II.

The separation of homologous pairs occurs
Separation of sister chromatids occurs
Crossing over/Recombination
Nuclei forms in preparation of 4 haploid cells
Independent Assortment

Meiosis I (3 Items)
Meiosis II (2 Items)

Determine the most accurate explanation of meiosis and clarify how this process guarantees that the resulting gametes contain haploid(half) number of chromosome.

Meiosis randomly chooses which chromosomes to retain, resulting in each genetically distinct gamete possessing a unique number of chromosomes.

Meiosis involves a single division process, producing two daughter cells that are genetically identical to the parent cell and maintain the same chromosome count.

Meiosis consists of two cycles of cell division, leading to four genetically unique daughter cells, each containing half the chromosome count.

Meiosis involves the duplication of chromosomes without dividing them, resulting in the formation of four genetically identical gametes, each containing the complete set of chromosomes.

Random mutations may arise in the DNA of cells during the initial stages of embryonic development.

Environmental stimuli can influence gene expression by activating or deactivating particular genes within the DNA of cells.

Cells compete for nutrients and that's why they look different

DNA sequences change over time causing the cells to not develop into the same type of cells
