Question

how many total offspring are shown on this pedigree chart? 28 17 2 4

Explanation:

Step1: Count the offspring in each generation

• First generation: 2 pairs (but they are parents, not offspring in the context of the whole chart's offspring count)
• Second generation: 4 individuals (they are offspring of the first - generation pairs)
• Third generation: 6 individuals (offspring of the second - generation pairs)
• Fourth generation: 7 individuals (offspring of the third - generation pair)

Step2: Sum up the counts

$4 + 6+7=17$

Answer:

17
