20. How is it possible to
obtain the probability of
emergence of a given
genotype formed of more than
one pair of different alleles
with independent segregation
from the knowledge of the
parental genotypes?

Taking as example the of
AaBbCc with aaBBCc, each
considered pair of it is possible to
which genotypes it can (as
in an independent ) and in
which proportion. x aa: Aa, aa (:1).
Bb x BB:BB, Bb (:1). Cc x Cc: CC, ,
cc (1:2:1). The genotype which the
probability is be determined isfor
example . For each pair of
genotype the formation probabilityis
: to aa, 0.5; to , 0.5; to
cc, 0.25. final result is obtained
multiplication of these partial
, 0.5 x 0.5 x, .5, resulting
0.0625.
