Question

The chromosomes in a homologous pair contain the same genes in the same locations. But one chromosome might have a different version of a gene than the other chromosome. Different versions of the same gene are known as alleles. Scientists have assigned a number to each homologous pair of chromosomes that make up a human's DNA. They use this numbering system to describe where specific genes are found on particular chromosomes. For example, the gene for ABO blood type in humans is found on chromosome 9. This gene has a specific location, called a locus, on the chromosome, but the allele can vary. So an individual could inherit the allele for blood type A from their mother, and the allele for blood type B from their father.Complete the paragraph. Each chromosome in a homologous pair is inherited from . Any two homologous chromosomes contain the same , but may have different.

Answer 1

Each chromosome in a homologous pair is inherited from a different parent. Any two homologous chromosomes contain the same genes, but may have different alleles.

Answer 2

Let’s have a look!

The chromosomes in a homologous pair contain the same genes in the same locations. 

But one chromosome might have a different version of a gene than the other chromosome. 

Different versions of the same gene are known as alleles. 

Scientists have assigned a number to each homologous pair of chromosomes that make up a human's DNA. 

They use this numbering system to describe where specific genes are found on particular chromosomes. 

For example, the gene for ABO blood type in humans is found on chromosome 9. 

This gene has a specific location, called a locus, on the chromosome, but the allele can vary. 

So an individual could inherit the allele for blood type A from their mother, and the allele for blood type B from their father.

Pretty straightforward, but if you need clarification about the above, please do comment! Thankfully, the answers you need are already in the text.

The paragraph:

Each chromosome in a homologous pair is inherited from [Blank 1]. Any two homologous chromosomes contain the same [Blank 2], but may have different [Blank 3].

Homologous pairs come from the “maternal” and “paternal” cells, so each chromosome would come from one of the parent cells! So Blank 1 should be “a parent cell”. See the bolded part about inheriting from a mother and a father?

The answers for Blank 2 and Blank 3 are also stated above!

Any two homologous chromosomes contain the same genes in the same locus (Blank 2), but may have different versions of the same gene, or alleles. (Blank 3)
