In a GUI I load a rgb image in axes1. After that I cropped one portion of the image and showing that cropped portion in axes2. But after cropping the size of the cropped portion is changed. Its zoomed. How to show the cropped porition in its actual size in axes2? Is there any option to stop that auto zoom?

In axes2, first display the original image, then put "hold on", and then display your cropped image. The axes will stay adjusted to what they were when you showed the first image.

I tried it. But then in axes2 both images are displayed at the same time. First the main image is displayed. And then in lefttop corner the cropped portion is displayed.

Then display zeros or some uniform image. Try this:
bigImage = imread('moon.tif');
subplot(1, 2, 1);
imshow(bigImage);
axis on;
smallImage = bigImage(250:300,50:300);
subplot(1, 2, 2);
imshow(zeros(size(bigImage)));
axis on;
hold on;
imshow(smallImage);
