So looking at multiple trait selection, there's a couple terms that we are going to talk about.
00:09
We're going to start with a term of tandem.
00:17
So essentially in tandem multiple trait selection, you are selecting one trait and then another.
00:28
So you're doing it one at a time.
00:31
And we do this because it's very common and it's easy and it's often used for a selection target or targeting a specific selection.
00:45
So an example of this might be that you have a certain organism, certain populations that you want to observe.
00:53
And for five generations, you select for the number of eggs that are laid.
00:58
And then the next five generations, you select for when puberty happens.
01:03
Right, so you're doing one thing and then another.
01:07
We utilize tandem because it helps us determine genetic correlations and how effective they are between the traits.
01:27
So now we're going to talk about another type of multiple trait selection, which is called independent culling levels.
01:38
So this one and the next one we're going to talk about are definitely not as common because they're not as easy, they're not as just point and shoot kind of thing.
01:48
But in independent culling levels, you are looking for minimum standards.
01:58
Minimum standards for the traits that you are observing.
02:01
So in this one, we're looking at multiple traits at once...
