Answer:
Spinal cord injuries are responsible for people not being able to move their bodies below a certain point. What determines how much of the body they can still move is the level of the spinal cord injury.
Explanation:
The central nervous system cannot communicate with the brain due to the spinal cord injury.
Answer: 1). A and B are both dominant (because A and B are codominant to one another)
2). E. All of the above
Explanation:
1). From the image above, A and B are both dominant because they are equally expressed when they occur in a pair (when they occur as blood type AB), also they are dominant because each of them expressed itself when it occurs in a pair with a recessive allele (IAi and IBi).
2). The children of a father with A blood and a mother with B blood will have all the four blood types: A, B, AB, and O. If each parent has a recessive allele, that is if each parent is heterozygous for his/her blood type (IAi for the father and IBi for the mother), the cross between them will produce all the four possible blood types.
See the attached punnet square for more information.
The answer is 50 percent.
Parent plant of genotype Rr will in meiosis produce haploid gametes which will carry either R allele or r allele. Since there are only two possibilities R or r, the probability that seed will get r gene is 1 of 2. This can be presented as 1/2, which is 50%.
Answer:
When replication mistakes are not corrected, they may result in mutations, which sometimes can have serious consequences. Point mutations, one base substituted for another, can be silent (no effect) or may have effects ranging from mild to severe.
