Question 6 You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered one. All of the FI are pink. Wh
muminat

Answer:

E (Red shows incomplete dominance over white)

Explanation:

This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.

Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.

In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.

What is the function of the structure labeled Y?
Rashid [163]

Hey there!

I'm assuming it's pointing to the wall in between the two sections of the heart.

We can go over the function of the blue section and red section of the heart. Though I must admit I am not well versed with hearts of birds, I will assume this is similar to a human one. The blue section <u>receives blood from the body which doesn't have any oxygen left in it,</u> and the red section <u>receives blood from the lungs, newly oxygenated.</u> This sector in between separates these two sections, and separates oxygen-poor blood and oxygen-rich blood.

Thus, your answer is option D.

Hope this helps, feel free to let me know if you have any additional questions about this specific problem!

They all border the state of Kentucky

They are Virginia's westernmost watersheds

Explanation:

Big Sandy, Clinch-Powell and Holston watersheds are all located in Virginia.

These watersheds are located in the west region of Virginia alongside the border with the state of Kentucky

They are located next to each other and all tree connect with Kentucky.

With their area they are not the smallest nor the largest watersheds in Virginia.

Big Sandy's area is 990 sq miles, Clinch-Powell's is 1.811 sq miles, while Holston watershed's area is 1322 sq.miles
