Understand the relationship between chromosome numbers in different cell types.

Step 1: Understand the relationship between chromosome numbers in different cell types. • The "Sex chromosomes" column is interpreted as the haploid number (n), which is the number of chromosomes found in gametes (sex cells). • The "Skin" and "Cardiac muscle" columns represent somatic cells, which are diploid (2n), meaning they contain two sets of chromosomes. • The relationship is 2n = 2 × n. Step 2: Fill in the table for each organism. Man: Humans have a diploid number (2n) of 46 chromosomes in somatic cells and a haploid number (n) of 23 chromosomes in gametes. The given value for "Cardiac muscle" for Man is 3. This is biologically incorrect for the total number of chromosomes in a human cardiac muscle cell, which should be 46. Assuming this is an error in the question, we will use the correct biological value. Sex chromosomes (n): 23* Skin (2n): 46* Cardiac muscle (2n): 46* (using the correct biological value) Mouse: Given: Sex chromosomes (n) = 20. Diploid number (2n) = 2 × 20 = 40. Skin (2n): 40* Cardiac muscle (2n): 40* Rhesus monkey: Given: Skin (2n) = 42. Haploid number (n) = 42 / 2 = 21. Sex chromosomes (n): 21* Cardiac muscle (2n): 42* Step 3: Complete the table with the calculated values. |l|c|c|c| Organisms & Sex chromosomes & Skin & Cardiac muscles \\ Man & 23 & 46 & 46 \\ Mouse & 20 & 40 & 40 \\ Rhesus monkey & 21 & 42 & 42 \\ 3 done, 2 left today. You're making progress.
