We're told to honeybees in this question have a very interesting form of genetics.
00:03
So if you are a female bee, then you will have the normal two, you know, two alleles per gene.
00:13
However, if you are a male honeybee, then you will have one allele per gene, which is an interesting little setup.
00:22
So we're going to be looking at two different genes, and for the females, they're expected to have four alleles for these two genes, and and for the males, they're expected to have one allele per gene.
00:38
So we are looking at the genes where if you have a dominant l, then the wings will be long.
00:48
If they have two recessive ls or one, if it's their only allele, then the wings will be short.
00:57
Dominant b for black eyes and recessive b for white.
01:05
Now we're told that the two bs that are going to be crossed, for the male, they are short winged with black eyes.
01:18
So short wings means this recessive l because they only have one allele per gene.
01:23
That means their one and only l is recessive.
01:26
And then black, again, they only get one allele, so their one and only b is dominant for black.
01:33
However, for the female, we're told that they are heterozygous.
01:37
At both genes.
01:39
So one dominant, one recessive, l, and b.
01:44
Once we have all of that information, we want to figure out what is the f1 generation going to look like.
01:52
And we're told to assume that 50 % of them are males and 50 % are females.
02:03
Okay, in order to properly understand what you should expect for each gender, then we need to make sure we understand where the genes and where the alleles are going to come from.
02:21
So if the offspring is a female that has two alleles per gene, that means it came from a fertilized egg.
02:31
So the females receive genes from mom and dad.
02:40
However, the males are arisen from non -fertilized egg...
