Question

In roses, purple flower color is determined by the dominant P allele, while pphomozygotes are white. The presence of long stems is determined by the dominant S allele, while ss homozygotes have short stems. Both mutations are completely penetrant.  A test cross was performed between a rose plant of unknown genotype with a white flowered, short stemmed rose plant (pp ss) and the following 200 progeny plants were obtained:

 

84 white flowers, long stems   

16 purple flowers, long stems                 

82 purple flowers, short stems             

18 white flowers, short stems          

 

Select two statements below that are TRUE.

options:

 

The P and S genes independently assort during meiosis.  

 

The map distance between P and S is 17 cM.

 

The genotype of the progeny plants with purple flowers and short stems is PP ss.

 

The map distance between P and S is 83 cM.

 

The homologs in the plant with unknown genotype are p S and P s.

 

The homologs in the plant with unknown genotype are P S and p s.
