Sagot :
The breeding of the genetics in a deer, in which the parents have both a
N and and a allele results a 0.25 chance of an albino coloring.
Response:
(a) 25%
(b) (0.5·N + 0.5·a)² = 0.25·N·N + 0.25·N·a + 0.25·N·a + 0.25·a·a
(c) The coefficient of the product (offspring) a·a is 0.25 which confirms the response in part (a)
What is Punnett square and how is it used?
A Punnett square is used for the prediction of the genotypes in a
breeding experiment.
The Punnett square for the possible gene combinations is presented as
follows;
[tex]\begin{tabular}{|c|c|c|c|}&& P2& \\&&N&a\\P1&N&NN normal &Na normal\\&a&Na normal&aa albino\end{array}\right][/tex]
(a) Number of possible gene combination resulting in albino coloring = 1
Number of possible gene combinations = 4
The percentage of the possible gene combination resulting in albino
coloring is therefore;
[tex]Percentage = \dfrac{1}{4} \times 100 = \underline{25\%}[/tex]
(b) The polynomial of each parent gene combination = 0.5·N + 0.5·a
The product that represent the possible gene combinations of an offspring = (0.5·N + 0.5·a)²
(0.5·N + 0.5·a)² = (0.5·N + 0.5·a) × (0.5·N + 0.5·a)
(0.5·N + 0.5·a)×(0.5·N + 0.5·a) = 0.25·N·N + 0.25·N·a + 0.25·N·a + 0.25·a·a
The product is therefore;
- (0.5·N + 0.5·a)² = 0.25·N·N + 0.25·N·a + 0.25·N·a + 0.25·a·a
(c) From the product of the polynomial, (0.5·N + 0.5·a)², the probability
and therefore, the percentage of the possible gene combinations that
result in albino, a·a is 0.25, which is 25%.
- The coefficient of a·a confirms the percentage of the possible gene combinations that result in albino in part (a) is 25%.
