Two genes are on separate chromosomes (i.e., unlinked). One homologous pair of chromosomes carries the 'A' and 'a' alleles, while another homologous pair of chromosomes carries the 'B' and 'b' alleles. Based on what you know about Independent Assortment and probability, what percent of the time will the following occur: 1. 'A' goes with 'B' and 'a' goes with 'b'? 2. 'A' goes with 'b' and 'B' goes with 'a'? Therefore, can we compute a distance of 60 map units for two genes by a two point cross? Yes or No. Why?

Three pt croSS (1)
Two genes are on separate chromosomes (i.e., unlinked). One homologous pair of chromosomes carries
the 'A' and 'a' alleles, while another homologous pair of chromosomes carries the 'B' and b' alleles.
Based on what you know about Independent Assortment and probability, what percent of the time will
the following occur:
1. 'A' goes with 'B' and 'a' goes with 'b'?
2. 'A' goes with 'b' and 'B' goes with 'a'?
Therefore, can we compute a distance of 60 map units for two genes by a two point cross? Yes or No.
Why?
Mendel observed 7 traits. Pea plants have seven chromosomes. It is now known that the traits studies
by Mendel were not on separate chromosomes. Do you think that Mendel accurately reported his
experimental findings?
