A man with type A blood marries a woman with typeb. Their offspring all have type AB blood. The pattern of inheritance is called

Answers

The pattern of inheritance is called codominance when the father has type A and the mother has type B and the kids have type AB blood. This is when the both of the alleles will show equal dominance/impact after mating. The type A blood has the gene pattern iAi or iAiA. The type B blood has the gene pattern iBi or iBiB. The correct answer to this question is "codominance."

Which cross will yield four phenotypes in the 1:1:1:1 ratio

Answers

The answer is RrYy x rryy.

It is known that the in dihybrid cross (a cross between two different traits), the phenotypic ratio between the offspring in the F2 generation is 9:3:3:1. To get phenotypes in ratio 1:1:1:1, there must be a cross between heterozygote for both traits and recessive homozygote for both traits. This can be concluded if these two traits are analyzed separately:
Parents:       Rr    x    rr
Offspring: Rr    Rr   rr    rr
So, the ratio is 2:2 or 1:1.
The same ratio is for cros Yy x yy.
Thus, the cross between RrYy and rryy will yield four phenotypes in the 1:1:1:1 ratio.
In the attached photo, 1/4 of the offspring are RrYy, 1/4 are Rryy, 1/4 are rrYy, and 1/4 rryy. The ratio is 1/4:1/4:1/4:1/4, which is the same as 1:1:1:1.

MULTIPLE CHOICE QUESTIONWhat is the test variable (independent

variable) here?


The additive anti-barnacle treatment


The number of barnacles on the boat


The amount of paint applied to the boat

Answers

Answer:

The number of barnacles on the boat

Explanation:

The number of barnacles of the boat is an independent variable because an independent variable is that variable that can stand alone or does not

changee or has no variation due to dependent variable.

It is not affected by changes in dependent variable. It's changes does not depend on dependent variable.

The number of barnacles on the boat is an independent variable and it changes does not depend on The amount of paint applied to the boat and The additive anti-barnacle treatment.

Final answer:

In the given question, the 'additive anti-barnacle treatment' applied to the boat is the independent variable. It can be manipulated to assess its effect on the number of barnacles on the boat.

Explanation:

In experimental research, an independent variable is the variable that is intentionally modified or manipulated by the researcher to observe the effect on the dependent variable. In this case, the test variable (or independent variable) you're inquiring about seems to be the 'additive anti-barnacle treatment' applied to the boat.

This variable is independently manipulated, because changes in its elements or levels (such as different types or amounts of treatment) might affect the dependent variable, which in this case could be the 'number of barnacles on the boat'.

How can an injury to a peripheral nerve cause loss of both sensory and motor functions?

Answers

The reason is that peripheral nerves have both sensory and motor fibers. 

Through these sensory fibers, peripheral nerves receive signal and send them to the brain. Also, through motor fibers, peripheral nerves send information to the muscles. When a peripheral nerve is damaged, the both functions will be lost.
