Answer:
Option C
Explanation:
Let the allele for black color be "B"
and the allele for white color be "b"
Since after F1 generation all the offspring have black body with white speckles throughout their feathers.
Thus the allele for black and white show co dominance.
Genotype of parent after F1 generation would be Bb for speckled chickens
Cross between two specked adults will produce -
Bb x Bb
BB, Bb, Bb, bb
Out of four offspring 1 is black (BB), 1 is white (bb) and two are speckled (Bb)
Thus 50% of the offspring will be speckled, 25% will be black, and 25% will be white.
Option C is correct
Ken and Kendra share 50% of their genes. Lara an Lonnie share 100% of their genes.
The fraternal twins are just siblings that share the same womb. Each of them starts it's development as separate egg that is fertilized by a separate sperm, so they are no more similar than the other siblings.
The biological (identical) twins, on the other hand, come from the same fertilized egg, thus they share the same genes.
Answer:
Phenylalanine.
Explanation:
The A site (aminoacyl) is the first binding site in the ribosome. In this case, in the exit site is GAC (Asparagine), next to it is CAU, for the Histidine referred in the question as reference, and then, in the A site you find UUU, that according to the genetic code translates in phenylalanine.
Shortness of breath is very common in the last trimester of pregnancy. This is because, the baby inside the uterus is growing and it starts to push the uterus that compresses the lungs above the diaphragm. This, leads to restricted expansion of the lungs while breathing and causes shortness of breath. Another reason for shortness of breath can be due to low iron content in the body.
If a pregnant woman in her last trimester reports occasional shortness of breath, the nurse should instruct her to:
1. take deep breath and start doing prenatal yoga
2. sleep on the left hand side
3. practicing good posture and standing straight
4. relax as much as possible
