Horses and zebras can be bred to produce a zorse, which is sterile. Which is most likely the reason zebras and horses are considered separate species?

Answers

Answer 1

Answer:

For an organism to be considered as same species, it is important that their progeny can mate and produce viable offspring for generations. In this case, the mating of zebra and horse does not produce a fertile offspring, hence, their offspring cannot produce future generation, so, they cannot considered to be in same species.

Moreover, there are difference in the number of chromosome in between zebra and horse, and the zorse's number of chromosome is also different from the zebra and horse. In a species, the number of chromosomes must be same, so, this is also a factor, why they are not considered as a same species.

Answer 2

Answer: Because they cannot breed together to provide fertile offspring. (If their children cannot have children they are most likely to be considered separate species)

Blood Type identifies the presence or absence of particular proteins embedded in the cell It is quicker and less expensive than DNA profiling Produces blood evidence but can still link a suspect to a crime scene or exclude a suspect The presence or absence of cell-surface proteins determines a person’s blood type. True or false?

Answers

True

Explanation:

Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body

Some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching

There are four major blood groups determined by the presence or absence of two antigens: A and B on the surface of red blood cells

In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present or absent creating the 8 most common blood types which are A+,A-.B+,B-O+,O-,AB+,AB-

Blood type is inherited and it is determined by the blood type of both father and mother

Blood type helps in DNA fingerprinting and forensic science and plays an important role in determining blood relations or to identify the suspect
