Accepted Answer

Hello, everyone. Here's our next problem. Homologous chromosomes have alleles of the same blank located at the same blank. So we need to fill in the correct words here. So let's recall that homologous chromosomes are a pair of matching chromosomes. They're usually given numbers. So inhuman. You'd say this is chromosome one or chromosome five and one inherited from each parent. Well the chromosomes have jeans on them and varieties of different varieties of a gene are called alleles. So we say these homologous this pair of matching chromosomes, they have matching jeans for the same thing on each. Those genes can come in different varieties and those varieties are alleles. So homologous chromosomes chromosomes have alleles of the same. The word we're looking for there is jean located at the same blank. So the location of a gene on a chromosome, the physical location of where that piece of D. N. A. Is. Look at the word located that gives us a key same Los I. L. O. C. I. So let's look at our answer choices and we see choice A says chromosome sequence. Choice B says jean low size. So Choice B is correct choi si says chrome it'd chromosome chroma tides. We look at our chromosomes. They look kind of like a little excess here when they have when they're connected by their centimeter there And the two sort of legs here. The X. R. The chroma tits. So that's not the word we're looking for. Um the alleles are of the gene and where the gene is located a lawsuit. So they, you know, this particular genes may be located right there is the low side of the gene, so Choice B. Gene and Lo sai is our correct answer. And that matching location in the pair of homologous chromosomes is what makes them suitable for pairing up before mitosis or mitosis. We'll see you in the next video.
