Question

number of chromosomes in a king crab gamete: 104
mice have 20 chromosomes in their gametes; how many chromosomes are in their somatic cells?
number of chromosomes in a mouse somatic cell:
the gametes of dogs contain 39 chromosomes; how many chromosomes are in their somatic cells?
number of chromosomes in a dog somatic cell:

Explanation:

Step1: Recall the relationship between gamete and somatic cell chromosomes

Gametes are haploid (\(n\)), somatic cells are diploid (\(2n\)).

Step2: Calculate for mice

Given \(n = 20\) (gamete of mice), then \(2n=2\times20 = 40\) (somatic cell of mice).

Step3: Calculate for dogs

Given \(n = 39\) (gamete of dogs), then \(2n=2\times39 = 78\) (somatic cell of dogs).

Answer:

40, 78
