So 50% this, 50% that. Now, in this particular case, things are quite simple because we only we only form one type of sperm cell that contains uppercase g, lower case g, lower case N. So lowercase g, lower case N. And that is 100% of the offspring. And so this always forms this. But this can form two. Now, if this combines with this, what we basically form is offspring number one that contains well, we basically have uppercase g, lowercase g, or it should be uppercase g with this green color and lowercase g with this green color and then lowercase and lowercase N. So lowercase N, lowercase N. The second type of offspring that is produced is so if this combines with this, we have lowercase g, lower case g, uppercase and lowercase N. And because this is 50% and 100%, so .5 times one gives us zero. Five.
