Apply the laws of probability and calculate the probability the offspring of the cousin marriage of 3 x 7 will have the trait. (enter a decimal fraction between 0.00 and 1.00)

0.16

Step-by-step explanation:

The calculation of probability by applying the is shown below:-

It is evident from the pedigree that the mode of inheritance is recessive and the characteristic is recessive that's also phenotype of disease is only seen if the genotype is aa.

The genotype of 1. In pedigree Can be either AA or Aa.

The chance that the offspring of the cousin marriage will have the characteristic is

which gives results

= 0.16
