Concept explainers
To determine: The genotypes of the offspring if a test cross occurs between a BbCc and bbcc individuals.
Introduction: Gregor Mendel is known for his exemplary role in the field of genetics. Due to his contributions, he is known as the father of genetics. Mendel suggested that genes are the elements responsible for inheritance, and each gene comes in pairs. Mendel also proposed the law of independent assortment, which stated that the alleles were inherited independently from each other.
Explanation of Solution
The genotypes of the offsprings obtained by a test cross between BbCc and bbcc are as follows:
bc | bc | bc | bc | |
BC | BbCc | BbCc | BbCc | BbCc |
Bc | Bbcc | Bbcc | Bbcc | Bbcc |
bC | bbCc | bbCc | bbCc | bbCc |
bc | bbcc | bbcc | bbcc | bbcc |
A test cross is a cross between the organism with an unknown genotype and with a homozygous recessive organism. The test cross helps in identifying the genotype of an organism. The ratio of the
