Otrada [13]
In flowering plants the gametophyte phases are reduced to a few cells dependant for their nutrition on the Sporophyte.                                                  The gametophyte comprises the main plant, while the diploid sporophyte is much smaller and is attached to the gametophyte. Both spores and the resulting ganetophyte are haploid, which means they only have one set of chromosomes. The mature gametophyte produces male or female gametes by mitosis. The fusion of male and female gametes produces a diploid zygote which then develops into a new sporophyte.

Four genes (A, B, C, D) are known to be located on the same chromosome. A series of crosses was completed to determine the recom
tatuchka [14]

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.
