Explanation:
In the given question,
suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.
The genotype for white, disc shape fruits is- AABB
the genotype for yellow, long fruits is- aabb
F1 progeny will be- AABB x aabb
AaBb
F2 cross- AaBb x AaBb
AB Ab aB ab
AB <em>AABB AABb AaBB AaBb</em>
Ab <em>AABb AAbb AaBb Aabb</em>
aB <em> AaBB AaBb aaBB aaBb</em>
ab <em>AaBb Aabb aaBb aabb</em>
The genotype of F2 cross are-
1. 9/16 A- B- disc-shaped (like F1)
2. 3/16 A- bb spherical
3. 3/16 aa B- spherical
4. 1/16 aa bb long.
Answer:
I believe the answer is A
Explanation:
The other reasons would not give enough reason for competition between populations.
Australia, Zealandia, and New Guinea are continental islands. These three regions share some physical features. All three have mountain ranges or highlands—the Great Dividing Range in Australia; the North Island Volcanic Plateau and Southern Alps in New Zealand; and the New Guinea Highlands in Papua New Guinea.
