Crossing over often occurs during prophase. how could scientists use an easy to measure trait that is linked to the gene responsible for a certain genetic condition to locate the disease causing gene?

Crossing over is the phenomena of the exchange of the genetic material between the non sister chromatid of the homologous chromosomes. The crossing over results in the  formation of recombinant progeny.

Linked traits are  close to each other and present on the same chromosome. The linked traits that are very close to each other and will not separate by the process of crossing over. This information is used to locate the disease condition.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. weight is the measure of the force of gravity on an objects's mass, while mass is the measure of how much matter there is in an object.
