In mice, the a mutation results in albino mice, while mice with at least one copy of the A allele are brown. The t mutation causes short tails, while mice with at least one copy of the T allele have long tails. Doubly heterozygous mice are testcrossed to albino short-tailed mice, and the 1000 progeny have the following phenotypes: 442 offspring are albino with long tails 458 offspring are brown with short tails 46 offspring are albino with short tails 54 offspring are brown with long tails Calculate the recombination frequency between the two genes.

In mice, the a mutation results in albino mice, while mice with at least one copy of the A allele are brown. The t mutation causes
short tails, while mice with at least one copy of the T allele have long tails. Doubly heterozygous F1 mice are testcrossed to albino
short-tailed mice, and the 1000 progeny have the following phenotypes:
442 offspring are albino with long tails
458 offspring are brown with short tails
46 offspring are albino with short tails
54 offspring are brown with long tails
Calculate the recombination frequency between the two genes. Express your answer as a decimal to two places.

Expert Solution
Step 1

Introduction : 

Recombination frequency is defined as the frequency of a single chromosomal crossover between two genes during meiosis. The recombination frequency, which rates the genetic linkage used to produce a genetic linkage map, determines the order of entry for each gene.
