B. change in the size of a chromosome.

C. change in two proteins.

D. change in the number of chromosomes in a cell.

Answer 1
Answer: sickle cell disease trait is passed on when one parent has a change in the a gene. when no the parents have a Chan g rd in the a gene then the chances of getting sickle cell disease is greater

Which lung sound possesses the characteristics of being louder and higher in pitch, with a short silence between inspiration and expiration and with expiration being longer than inspiration?A) BronchovesicularB) VesicularC) BronchialD) Tracheal

Answers

Answer:

C. Bronchial

Explanation:

The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.

The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.

The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).

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.

Answer:

RrYy x rryy was verified correct on test

Explanation: jcAlmighty is correct and provided helpful data. just took odyssey ware bio test. Question: Which cross will yield four phenotypes in the 1:1:1:1 ratio? A. rryy x rryy, B. RrYy x rryy, C. RrYy x RrYy, D. RRYY x rryy.       B. RrYy x rryy was correct
