Based on the "DRAW IT" section and Figure 23.7, if a bin contains six white balls representing CW alleles and the frequency of CR alleles needs to remain 0.8 80% , how many red balls representing CR alleles should be in the bin?

  • A: 18
  • B: 24
  • C: 30
  • D: 4

Explanation

If there are 6 white balls CW alleles and they represent 20% 0.2 of the total alleles, then the total number of balls N can be calculated as 6 / 0.2 = 30. If CR alleles constitute 80% 0.8 of the total, then the number of red balls CR alleles should be 0.8 30 = 24.
