Chromosomes, Mapping, and Meiosis-Inheritance Connection

If results of recombination do NOT follow Mendel's Law of Independent Assortment, genes are likely to be - - - 

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

Which genes are most likely linked?

• genes 1 & 2
• genes 2 & 3
• genes 3 & 4
• genes 1 & 4

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
