WebbASK AN EXPERT. Science Biology Albinism in humans is a relatively rare recessive condition. Let the allele for normal pigmentation be A and the allele for albinism be a. Therefore, individuals with the genotypes AA and Aa are normally pigmented individuals and aa are albinos. Suppose that in the US the frequency of albinos is 1 in 10,000. WebbMendel inferred that when a heterozygote forms its sex cells, the allelic genes segregate and pass to different gametes. This is expressed in the first law of Mendel, the law of segregation of unit genes. Equal numbers of gametes, ovules, or pollen grains are formed that contain the genes R and r. Now, if the gametes unite at random, then the F ...
