Answer:
CPT® Index - 96040
icd-10-cm code - Q99.2
Explanation:
 Here in this case the diagnosis came out with fragility in X chromosome. This is some thing related with medical genetics. Hence, the CPT® Index for this scenario would be 96040. As per the American Medical Association, CPT® Index 96040 cover cases that fall into the category of “Medical Genetics and Genetic Counseling Services” which also involves counseling either with the patient or family for 30 minutes. The icd-10-cm code – Q99.2 deals with the problems associated with genetic abnormality
Hence, the answer is 
CPT® Index - 96040
icd-10-cm code - Q99.2
 
        
             
        
        
        
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation. 
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.  
 
        
             
        
        
        
 Although the dolphin lives in the sea, it is not a fish - it's a mammal.
It makes the most sense if you read it aloud. 
        
             
        
        
        
Answer:
When the pollen tube grows into the ovule
Explanation:
Simmilar to animals, fertilization occurs when the egg (ovule) and the sperm join together to produce a new individual. In flowers, when the pollen tube grows into the ovlue is when pollen and ovule join together and fertilization occurs. A new seed is the produced, ready to produce a new individual.
 
        
             
        
        
        
The most consistent way to obtain information about the evolution of species is to look at the fossil record. Another is to observe the differences between species currently on earth. Another is to use carbon dating.
