tall, pink, happy 522
dwarf, blue, gloomy 497
tall, pink, gloomy 12
dwarf, blue, happy 18
tall, blue, happy 79
dwarf, pink, gloomy 83
tall, blue, gloomy 110
dwarf, pink, happy 107
Total 1428
The highest number of progenies belongs to the parental type and the lowest number of progenies are the progenies which undergone the double crossover event.
So We can conclude that the gloomy and happy alleles are present in the middle
If we want to find out the distance between the gloomy and dwarf then we need
to find out the crossover frequency and divide it by the total number of progeny
Stall, pink, gloomy 12
dwarf, blue, happy 18
tall, blue, gloomy 110
dwarf, pink, happy 107
Linkage distance = total number of recombinant * 100 / total number of progeny
= 247*100/1428
= 17.29
So, map distance between gloomy and dwarf is 17.29 map units or 17.29Cm
If we want to find out the distance between the gloomy and blue then we need
to find out the crossover frequency and divide it by the total number of progeny
Stall, pink, gloomy 12
dwarf, blue, happy 18
tall, blue, happy 79
dwarf, pink, gloomy 83
Linkage distance = total number of recombinant * 100 / total number of progeny
= 192 *100/1428
= 13.44
So, map distance between gloomy and blue is 13.44 map units or 13.44 Cm
So the gene order is Blue Gloomy dwarf
I need the steps to how to work this problem out. Three linked autosomal loci were...
Three linked autosomal loci were studied in smurfs. Locus Dominant Allele Recessive Allele Color Blue Pink Mood Happy Gloomy Height Tall Dwarf Pure breeding pink, happy, tall smurfs were mated to pure breeding blue, gloomy, dwarf smurfs. The F1 were testcrossed and the testcross progeny are given below. Phenotype Number pink, happy, tall 532 blue, gloomy, dwarf 517 pink, gloomy, tall 97 blue, happy, dwarf 84 blue, happy, tall 103 pink, gloomy, dwarf 111 blue, gloomy, tall 14 pink, happy,...
