Answer:
<h2>50 cM or more far apart
.</h2>
Explanation:
1. The largest possible map distance is 50, it represents that two genes are found at opposite ends of a chromosome or are 50 cM apart from each other or they are found on different chromosomes
.
2. Genes found at opposite ends of a chromosome behave as if they are on different chromosomes.
3. As given A-B 50%, means that recombination frequency is 50%.
The recombination frequency(RF), 50% means that either two genes are located on different chromosomes inheriting independently or when they are widely separated on the same chromosome with far distance.
4. As given here, four genes named A, B, C, and D are known to be located on the same chromosome. so A-B are 50 cM or more far apart from each other.
Endothermy is the trait that enables an organism to keep its internal body temperature constant. For example, humans shiver to keep warm should they feel cold and want to maintain homeostasis. This would not apply to reptiles, as they are cold-blooded and warm their bodies through different means.
