Once upon a time, there was a cell. It was moving around the primordial soup trying to make it in that harsh world. All of a sudden, it encountered a small prokaryotic cell. To be honest, the cell was feeling a little lonely and it was happy to come across somebody to share the habitat with. The two cells started spending a lot of time together, just quietly coexisting. The first cell started thinking how it would be so much easier to survive if the other, small cell were to live with me. I could provide safety and shelter, and the small cell can pay me back by providing me with the energy I need for my daily metabolic processes. The cell was hesitant for a second, but then bravely said ''Hey, what do you think about symbiosis?''. And the rest is (endosymbiotic) history.
As a matter of terminology, albino guinea pig actually refers to a white fur guinea pig, whose genotype is homozygous recessive (bb).
If it crossed with a black fur guinea pig and gave 5 black fur offsprings, there is a good chance that the black fur parent is homozygous dominant (BB).
The Punnett square would be as follows:
B B
b Bb Bb
b Bb Bb
So they are all heterozygous black fur offsprings.
However, it is not impossible that the black fur parent be heterozygous, namely
B b
b Bb bb
b Bb bb
Giving a 50% chance on each colour. Thus it is possible (with probability 1/32) that all five offsprings are heterozygous black fur if one of the parents was heterozygous.
In the second case, a homozygous recessive and a homozygous dominant parent will never give a white offspring. So it is sure that the black fur parent is heterozygous, with the following Punnett square:
B b
b Bb bb
b Bb bb
With a 50% probability for each of Bb (black fur) and bb (white fur).
the distribution 4,3 demonstrates this perfectly.
