Radioactive decay process is a type of process in which a less stable nuclei decomposes to a stable nuclei by releasing some radiations or particles like alpha particles , beta particles or gamma-radiations. The radioactive decay follows first order kinetics.
Alpha particles are helium nuclei, beta particles are electrons and gamma radiations are electromagnetic radiations which are released in the form of energy.
The genotype would be X'Y for the father (he would be colorblind) The genotype would be X'X for the mother (she would be a carrier) The offspring would be X'X' _ X'X_ X'Y_ XY The ratio would be 1:1 normal to colorblind Hope this was helpful(;
