So imagine you have a group of people and you want to know how many children they will have in the future. The bisexual Galton-Watson process is like a game where we try to figure out how many children each person will have on average.
Now, let's say that each person in the group can either be male or female, or bisexual which means they like both genders. We also assume that each person has a certain probability or chance of having one child, two children, three children, and so on.
What we do is we gather all this information and then we use it to simulate how many children each person will have. We also make sure that the children can also be male, female, or bisexual.
We then repeat this process multiple times so that we can get an idea of the average number of children each person will have over multiple generations.
Overall, the bisexual Galton-Watson process helps us understand the probability of how many children each person in a group will have over time, based on certain assumptions about gender and childbearing.
