Nоndisjunctiоn during meiоsis cаn negаtively аffect gamete formation. A model showing a possible nondisjunction event and its impact on gamete formation is shown in Figure 1. The first part of the figure shows a cell that has 5 pairs of chromosomes lined up at the equator of the cell. Each chromosome is composed of 2 chromatids. An arrow points to the next part of the figure that shows the same cell with the chromosomes starting to separate. 4 chromosomes and an additional unseparated pair of chromosomes are shown on the left side of the cell. 4 chromosomes are shown on the right side of the cell. Arrows point from the cell to the next part of the figure that shows 2 cells. One of the 2 cells has 6 chromosomes, each composed of a pair of chromatids, all in a single line along the equator of the cell. The other cell has 4 chromosomes, each composed of a pair of chromatids, all in a single line along the equator of the cell. Arrows point from each cell to 2 more cells in the final part of the figure. The 2 cells derived from the cell with 6 chromosomes each have 6 chromosomes. The 2 cells derived from the cell with 4 chromosomes each have 4 chromosomes. These four cells are labeled Gametes. Figure 1. Model of a nondisjunction event Which of the following best describes the most likely impact on an individual produced from fertilization between one of the daughter cells shown and a normal gamete?
Which оf the fоllоwing result from knowing the sequence of bаses in the humаn genome? It mаy enable scientists to identify all the genes expressed in humans. It may help scientists determine which genes are responsible for different genetic diseases. It may help scientists determine which genes contribute to different types of cancer. The sequence of bases can be compared to the sequence in different organisms to see how humans are related to other organisms at the molecular level.
