In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex

chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant.
This is one possible cross (above) for the X-linked condition known as hemophilia. Which pair of parents is most likely to have a hemophiliac daughter?

Kyle wants to get rid of beetles that are in his garden, he notices in areas that in areas that have a certain type of fertilize
EleoNora [17]

Answer: Is the fertilizer supporting the growth of beetles?

Explanation:

Here, Kyle wants to get rid of beetles in his garden but he observes that in an area where there is fertilizer there are more beetles. Thus, Kyle can frame the hypothesis that, "Is the fertilizer supporting the growth of beetles?". This hypothesis is forming the basis of experimental trials that can be done on beetles who were exposed to fertilizer and those who were not in laboratory conditions to check whether fertilizer is effective in supporting the growth of beetles. If the fertilizer is useful in supporting the growth then it should not be used in the garden.

Find, in km/h, the rate at which a car travels if it<br>goes 38.5km in 35 min.​
dimaraw [331]
Use this to help you. So here velocity is not given… so we have to calculate velocity of the car from given data. Car travel 60 km in 35 minutes. Frist of all we have to convert 35 minutes in hours by deviding 35 to 60 hour = 35/60

Next we have to calculate distance in kilometres so distance =velocity ×time.

Velocity =distance / time

Velocity =60/(35/60)

Velocity=3600/35

Distance = velocity ×time

In one hour… it will travel…

Distance =(3600/35) ×1.

By dividing you will get the answer…hope it will

Imagine that smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one oc
Keith_Richards [23]

Hello! Your answer is A, blue is dominant to white.

A dominant gene means that it is always expressed if present, no matter what other genes there are. For example, if there is a dominant blue gene, and a recessive red gene, blue will be expressed.

In this case, we see that all three children are blue. This shows that blue is most likely dominant, and white is recessive.

Let's approach the other case, that white is dominant to blue. If white is dominant, then the blue smurf must have two blue recessive traits, and the white smurf would either have two white dominant traits, or one white and one blue trait. The only possible way the children can have a blue color is if the white smurf is heterozygous (meaning it has two different genes, in this case one blue and one white), and passes down the recessive gene three times. As you can see, this is very unlikely.

If white and blue are codominant, then the children would have a mixture of the two genes. (Most likely). This is not the case.

Therefore, your answer is A.

Hope this helps!
