How to solve probability in genetics?
The empirical probability of an event is calculated by counting the number of times that event occurs and dividing it by the total number of times that event could have occurred.

Does mom or dad go on top of Punnett square?
A Punnett Square consists of a table with four quadrants. The dams genotype is listed at the top of the table and the sires genotype is listed on the side. Start by separating the parents genotypes into the two alleles they can give to their puppy.
What is the chance of a parent passing one of their two alleles to an offspring?
For each child that couple has, each parent will pass on one or the other of those two alleles. This is shown in figure 1. This means that each one of their children has a 50 per cent chance of having blood group A (AO) and a 50 per cent chance of having blood group O (OO), depending on which alleles they inherit.
How do you solve a Punnett square step by step?
The steps for completing a Punnett square are: Determine the genotypes of the parents. Write down the possible gametes for each parent. Arrange the parents gametes around the edges of a Punnett square. Fill out the offspring squares. Interpret the results.
What is a genetic cross of two plants results in offspring with 9 3 3 1 ratio for a particular trait?
A dihybrid cross has an expected ratio of 9:3:3:1 where 9/16 individuals show the dominant phenotype for both genes. The data from plecostomus here closely reflects this ratio.
