The more polar A compound moves ahead of the less polar B compound.

Explanation:

The analytical process that involves the separation of colored substance or chemicals is named as paper chromatography, a replacement of thin-layer chromatography. In this method, there is the use of two solvents and rotation of paper at 90^0. It helps in isolating two complex compounds of equal polarity.

A non-polar mixture of solvent is required in the mobile phase of this method. In accordance with the retention factor of this process, the more polar compound A will go further than compound B as the solvent is non-polar.

The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet
