Hey there!
The fundamental units of matter are called atoms. All matter, including liquids, solids and gases, are made up of these tiny building blocks.
Hope this helps !
Answer:
AA, Aa and aa genotypes will be produced.
Explanation:
If two birds with AA and aa genotypes are crossed, 4 offspring with Aa phenotype may be produced in F1 generation.
P generation: AA x aa
/ \ / \
F1 generation: Aa Aa Aa Aa
When these F1 generation birds will be allowed to breed, the genotype of the F2 offspring will be as under:
Aa x Aa
/ \ / \
F2 generation: AA Aa Aa aa
3 types of genotypes AA, Aa and aa will be produced in F2 generation. Their ratio will be AA : Aa : aa = 1 : 2 : 1.
