What happens to a microbes membrane at colder temperature?
Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be.
What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle?
What classes would be least frequent if locus f is in the middle?
What classes would be least frequent if locus w is in the middle?
