A hypothesis becomes a scientific theory when it has been thoroughly tested, and when whoever made the hypothesis now has proof of why their hypothesis was correct/incorrect.
If the parental genotypes are homzygous, the F1 birds would be heterozygous while all the F2 offspring would have the wild-type phenotype.
<h3>Monohybrid crossing</h3>
Based on the assumption that the wild-type genotype is AA and the slow feathering genotype is aa.
A cross between AA and aa:
AA x aa
F1 Aa Aa Aa Aa
One F1 male (Aa) is then crossed with a wild-type female (AA):
Aa x AA
AA AA Aa Aa
Genotypic proportion: 2 AA:2 Aa
Phenotypic proportion = 100% wild-type
