Why are the insides of my tomatoes yellow?
My tomatoes have turned very red, but when I cut into them, they are more yellow than red, especially near the stem. They are also fairly meally and do not have a lot of taste. Is it likely the kind of tomato plant I bought or the growing conditions? It has been a hot summer in Connecticut, but I do water every day if needed.

It can be both.
Tomatoes are best when planted based on your area. The ones you buy at the big box stores (Like Lowe's, Home Depot, Wal-Mart, etc) are bred to do ok in the widest possible climates and are typically hybrids. But they can't cover everything. They are the best average tomato you can buy, pretty much.
But, if you have extreme conditions or conditions outside the average, these tomatoes can be less than stellar.
If you are growing heirlooms, then I will say an emphatic Yes! that variety makes a huge difference. A tomato bred for South America would not do well where you are and would not taste good.
I like to recommend that you take a good look at local heirlooms. In a historic area like yours (anywhere East Coast, really), there will be tomatoes that have been grown for decades that grow well in your area. Don't rely on what local giant stores offer, but instead look at what your local master gardening group or extension service considers to be great tomatoes for your area and I think you will be happier with your results.
