Text-figure 1. Diagram showing expectancy for achondroplasic reaction in 

 the F 2 generation if the gene for this factor is located in different chromosomal 

 pairs in the two parent breeds. If it is assumed that the achondroplasic gene 

 is carried in the round gray chromosome of the female, and the long black 

 chromosome of the male, there will be sixteen possible combinations in the F.- 

 generation, as shown at the bottom of the diagram. From K. Belar.
