Answers

Mendel's experiment with garden peas would not have been successful if he had chosen traits without clearly dominant and recessive forms. So, it's C.

What are traits?

Traits may be defined as the expression or manifestation of the desired characters which are taken into the consideration.

Mendel selected two traits for each character in his pea experiment, i.e. dominant and recessive.

Therefore, the correct option for this question is C.

squirrels and chipmunks compete for the same food source. what is most likely to happen to the degree of competition between these 2 species if their food became scarce?

Answers

The competition will increase until the population size decreases because of the lowered carrying capacity of the environment. Then it will return to normal competition

Answer:

The correct answer would be increased in the degree of competition for the same food source.

Explanation:

Squirrels and chipmunks already share a common food source and competing for it. So, if the food became scarce there will be an increase in their competition for the food.

Squirrels and chipmunks will fight and display for the food as it is not in enough and there was already competing for the food.

Thus, the correct answer would be increased in the degree of competition for the same food source.

How do genes mix in humans?

Answers

In the X and Y chromosomes. 50% of your mom's genes are in the X chromosome, and 50% of your dad's in the Y.
Technically, it’s completely possible because DNA is just DNA. It doesn’t matter where it’s come from. In the lab, you can put jellyfish genes into mice, you can put human genes into bacteria, you can put worm genes into yeast. It’s all DNA. It’s all the same kind of nuts and bolts. If you put a gene in that’s kind of got the right bits and bobs, it will be expressed. That means it will be active and it will make a protein because that’s what genes do. They make little recipes that cells use to make different proteins. Now, that’s what genes do. The difficulty comes when you say, if you put certain genes into different species, would it give that species some new power? So for example say, if you put an olfactory receptor, something involved in smelling from a dog into a human, would a human be able to suddenly smell all these different things? The answer is probably no because one gene doesn’t just give a big characteristic like that. So, one gene is not responsible for super accurate sight or the smelling ability of dogs, or the hearing ability of foxes or something like that.
