Question

(GENETICS) With quinea fowls the gene for black colour (B) is dominant over the gene for white (b) Two heterozygotic black quinea fowls are crossed. Use a schematic representation to show the possible genotypic results that would be expected in the F1-generation.​

Answer 1

In the cross between two heterozygotic black guinea fowls (Bb x Bb), the possible genotypic results in the F1-generation can be represented using a Punnett square:

| B | b |

-----------------------------

B | BB | Bb |

-----------------------------

b | Bb | bb |

-----------------------------

The genotypic ratio in the F1-generation would be 1 BB : 2 Bb : 1 bb, where BB represents homozygous black, Bb represents heterozygous black, and bb represents homozygous white individuals.
