Final answer:
An example of a D/G reciprocal translocation that results in 45 chromosomes is the Robertsonian translocation between chromosomes 14 and 21 in which the long arms of both chromosomes fuse together. This type of translocation can lead to genetic disorders like Down syndrome.
Step-by-step explanation:
An example of a D/G reciprocal translocation that results in 45 chromosomes is when a segment of DNA transfers between chromosome 14 and chromosome 21. This is known as the Robertsonian translocation between chromosomes 14 and 21. In this translocation, the long arm of chromosome 14 fuses with the long arm of chromosome 21, resulting in one large chromosome and one small chromosome.
This type of translocation can lead to various genetic disorders, such as Down syndrome. In individuals with Down syndrome, instead of having two copies of chromosome 21, they have one complete copy and one copy that is attached to chromosome 14.
It's important to note that translocations can have different outcomes depending on which specific chromosomes are involved and where the breakpoints occur.
