Punnett Square for Genetic Probability Calculation

To calculate the probability of a child having a small number of teeth and five fingers based on the given genetic information, we can use a Punnett square. The genetic information provided is as follows:

- Parent P (female): AaBb - Parent P (male): Aabb

Punnett Square:

| | Aa | aB | Ab | ab | |---|----|----|----|----| | Aa | AA | Aa | Ab | ab | | ab | aA | aa | ab | ab | From the Punnett square, we can see that the possible genetic combinations for the offspring are: AA, Aa, Ab, aa, aA, ab, ab, ab.

Probability Calculation:

The probability of the child having a small number of teeth (a) and five fingers (b) can be calculated by determining the frequency of the "aabb" genotype in the possible genetic combinations.

The "aabb" genotype appears once in the Punnett square, out of a total of 8 possible combinations.

Therefore, the probability of the child having a small number of teeth and five fingers (aabb) is 1 out of 8, which can be expressed as 12.5%.
