• shuffled during meiosis
• linked
• inherited
• on separate chromosomes

Which genes are most likely linked?

Genes that are located in the same chromosome?

• Chromosome Map

• Genetic Recombination

• Linked Genes

• Fruit Fly

Linked genes are

• located on different chromosomes of the same size and shape
• located on the same chromosome
• rarely inherited together

Crossing-over of parts of chromosomes:

• has no effect on genetic linkage
• usually decreases the number of genetic combinations in a population
• can increase the number of genetic combinations in a population

According to _______, genes that are closer together on a chromosome, have a higher chance of being inherited together.  

• Gene Linkage
• Polygenic
• Pleiotropy
• Epistasis

What charge is DNA?

• positive
• negative
• neutral
