1.

Frequencyof an autosomal recessive lethal gene is 0.4 Frequency of carrier in a population of 200 individuals isA. 72B. 96C. 104D. 36

Answer» Correct Answer - B
Frequency of recessive allele is 0.4 Frequency of domint allele shall be 0.6 (1.0-0.4=0.6)
Frequency of carrier (2 Aa) would be `2xx0.6xx0.4=0.48` and hence 96 out of 200 As the stage of lethality is not mentioned it is presumed that the same willnot occur in the embroyo stage.
