Through a microscope you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15 This condition is an example?
translocation
What is the chromosome number of gamete?
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).

How many chromosomes are in a homologous pair?
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
Suppose your looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15?
An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.
