A pure breeding pea plant with the dominant phenotype of character A and recessive phenotype of character B was crossed with another pure breeding plant with the recessive phenotype of A and dominant phenotype of character B. A offspring of this cross was crossed with a homozygous recessive for both the characters – A and B. The following results are obtained 22 were phenotypically dominant for A and recessive for B.
4 were phenotypically dominant for both A and B.
4 were phenotypically recessive for both A and B.
24 were phenotypically recessive for A and dominant for B.
These results show that
A
Genes A and B are linked
B
Independent segregation of genes A and B
C
Mendelian dihybrid inheritance
D
Polygenic inheritance
Answer
Genes A and B are linked
