1. Write the karyotype of a male dog with deletion at the 3rd band of 2nd region of chromosome 4,long arm

The karyotype of a normal male dog (Canis lupus familiaris) is 78,XY, meaning it has 78 chromosomes in total, including the sex chromosomes (XY).

Since the question specifies a deletion at the 3rd band of the 2nd region of chromosome 4, long arm (q arm), we indicate this deletion using del(4q23) in cytogenetic notation.

Final Answer:

78,XY,del(4q23)

This means the dog has 78 chromosomes, is male (XY), and has a deletion at band 3 of region 2 on the long arm (q) of chromosome 4.

2. Write the karyotype of a plantain where by the last chromosome of the triploid has a cut on the short arm, region 2,band 5,short arm

The karyotype of a triploid plantain is 3n = 33, meaning it has 33 chromosomes instead of the normal 22.

Since the question says the last chromosome (33rd) has a cut on the short arm (p), at region 2, band 5, we write it as del(33p25).

Final Answer:

3n = 33, del(33p25)

This means the plantain has 33 chromosomes, and the 33rd chromosome has a missing part on the short arm at position p25.
