1. Which cells in a body will have the haploid number of chromosomes?
Haploid cells are those that contain only one set of chromosomes, which is half the diploid number. In humans and most organisms, haploid cells are gametes, which are the sex cells: sperm in males and eggs in females. These cells are produced through the process of meiosis.
2. How many chromosomes are in a chimpanzee's body cells? How many chromosomes are in chimpanzee gametes?
Chimpanzees (Pan troglodytes) have 48 chromosomes in their body (somatic) cells, which is the diploid number (2n = 48). Consequently, the number of chromosomes in their gametes (sperm and egg cells) is half of that, resulting in 24 chromosomes (n = 24) for each gamete.
3. Why is a diploid number always even?
The diploid number is always even because it consists of two complete sets of chromosomes: one set inherited from the mother and one set from the father. Since each set contains a complete number of chromosomes, and they contribute equally, the total count of chromosomes (diploid) is the sum of two equal parts, which results in an even number.
4. If you were asked to organize the data from this table into a graph, which kind of graph would you choose? Explain your choice.
The appropriate type of graph to choose would depend on the nature of the data presented in the table.
-
Bar Graph: If the data involves comparing different categories or groups (e.g., the number of chromosomes in different species), a bar graph would allow for a clear comparison across these categories.
-
Line Graph: If the data represents changes over time or a relationship between two continuous variables, a line graph would visually illustrate trends effectively.
-
Pie Chart: If the data depicts proportions of a whole (e.g., the percentage of cell types in a population), a pie chart can represent the data as parts of a whole.
Ultimately, the choice of graph should clarify the information presented, emphasize significant features, and make the data easy to interpret.
