Question

the number of chromosomes in a cell varies with the cell type and organism. tigers, king crabs, mice, and dogs are all diploid organisms. the somatic cells of tigers have 38 chromosomes; how many chromosomes are in their gametes? number of chromosomes in a tiger gamete: the somatic cells of king crabs have 208 chromosomes; how many chromosomes are in their gametes? number of chromosomes in a king crab gamete:

Explanation:

Step1: Understand the relationship between somatic cells and gametes

Somatic cells are diploid (\(2n\)) and gametes are haploid (\(n\)).

Step2: Calculate the number of chromosomes in tiger gametes

Given that the number of chromosomes in tiger somatic cells (\(2n = 38\)). To find \(n\) (gamete), use the formula \(n=\frac{2n}{2}\). Substitute \(2n = 38\) into the formula: \(n=\frac{38}{2}=19\).

Step3: Calculate the number of chromosomes in king - crab gametes

Given that the number of chromosomes in king - crab somatic cells (\(2n = 208\)). Using the formula \(n=\frac{2n}{2}\). Substitute \(2n = 208\) into the formula: \(n=\frac{208}{2}=104\).
