In Poultry, the Genes for Rose Comb ( R )

question 76

Short Answer

In poultry, the genes for rose comb ( R ) and pea comb ( P ) produce walnut whenever they occur together ( R _ P _); single-combed individuals have the homozygous condition for both genes ( rr pp ).
(a) Give the F ₁ and F ₂ phenotypic results of a cross of a pure-breeding rose comb ( RR pp ) with a pure-breeding pea comb ( rr PP ).
(b) Give the phenotypic results of a cross of Rr Pp x rr Pp .
(c) Give the phenotypic results of a cross of RR Pp x rr Pp .
(d) Give the phenotypic results of a cross of Rr pp x rr Pp .
(e) Give the phenotypic results of a cross of Rr Pp x rr pp .
