Step 1
a) Punnet square implies that there are 4 total gene combinations, namely NN, Na, Na, aa.
One one gene combination is devoid of even a single N.
Therefore the probability of albino coloring =14
=0.25
Percentage of albino coloring =25%
b) Each parent deer has half N genes and half a genes.
Modeling genetic makeup of each parent
=0.5N+0.5a
As there are two parents, genetic makeup of offspring is modeled in the form of polynomial (0.5N+0.5a)2
=(0.5N)2+(0.5a)2+2(0.5N)(0.5a) (Standard algebraic identity)
=0.25N2+0.25a2+2(0.5N)(0.5a) (Evaluate powers)
=0.25N2+0.25a2+0.5(Na) (Simplify)
Coefficients in above polynomial represent the probabilities of each kind of offspring.
