In each homologous pair one chromosome is from mother and the other is from father, thus we conclude that in a diploid human cell 23 chromosomes are from father and 23 chromosomes are from mother and collectively they form 23 pairs. Both the chromosomes of each pair are always identical.

Then you need to go to Vet school for four years to get your doctorate. Vet school is the single hardest graduate program to get into (much harder than medical school). There are only 28 Vet schools in the US.

The first step to becoming a veterinarian in the U.S. is attending undergraduate school. According to the U.S. Bureau of Labor Statistics (BLS), some veterinary colleges require applicants to hold only 45-90 undergraduate hours; however, most students enter veterinary school with bachelor's degrees (www.bls.gov).fter gaining admittance, students complete four years of veterinary school to earn a Doctor of Veterinary Medicine (D.V.M.). The first two years of veterinary school typically focus on basic science education in the classroom and laboratory.
