The cross of a green budgie and a yellow budgie produces offspring that are 12 green, 4 blue, 13 yellow, and 3 albino. what are
the genotypes of the parents?
1 answer:
Genotypes:
blue: yyBb or yyBB
yellow: Yybb or YYbb
albino: yybb
green: YyBb or YYBB or YyBB or YYBb
32 offspring
The cross between the parents need to be like: Yybb x YyBb
that way, if you follow the table down below, 6/16 will be green (it's the same as saying 12/32); 6/16 are yellow (about the same as 13/32); 2 albinos, and 2 blue offspring (2/16 is the same as 4/32 and close to 3/32).
