The genotype of back cross progeny from a homozygous brown fish with a homozygous white fish, and backcrossed the F 1 with the homozygous white parent. Introduction: Medaka is a small fish, which is found in Japan. The fish are of four colors; red, blue, brown, and white. The color of the fish is determined by the genes at two loci; B, b, and R, r. Brown color is determined by two dominant loci (B_R_), blue color of the fish is determined by one dominant allele (B_rr), red color of the fish is determined by only one dominant allele at the R locus ( bbR _), and white color is determined by a recessive allele at both locus (bb rr).

Summary Introduction

To determine:

The genotype of back cross progeny from a homozygous brown fish with a homozygous white fish, and backcrossed the F₁ with the homozygous white parent.

Introduction:

Medaka is a small fish, which is found in Japan. The fish are of four colors; red, blue, brown, and white. The color of the fish is determined by the genes at two loci; B, b, and R, r. Brown color is determined by two dominant loci (B_R_), blue color of the fish is determined by one dominant allele (B_rr), red color of the fish is determined by only one dominant allele at the R locus (bbR_), and white color is determined by a recessive allele at both locus (bb rr).
