Can a person with 45 or 48 chromosomes survive?

Answer 1

Someone with 45 chromosomes can survive if the missing chromosome is a sex chromosome.

48 chromosomes would be 2 trisomies...if one was a trisomy of chromosome 21 and the other trisomy involved one of the sex chromosomes this would probably produce a living offspring.

Other trisomies tend to have more negative effects and it is unlikely that multiple trisomic individuals would survive.

Answer 2

Yes - although it is quite rare. Trisomies, where a person has an extra copy of one chromosome (47 in total) are slightly more common.

Tetrasomy is when a person has four, instead of the usual two, copies of a certain chromosome. This will result in a person with 48 chromosomes.

Answer 3

Yes, individuals with 45 or 48 chromosomes can survive, although it may result in genetic disorders or conditions such as Turner syndrome (45 chromosomes) or Down syndrome (48 chromosomes). The impact on health and development can vary depending on which chromosomes are affected and the specific genetic changes present.

Answer 4

YES. in the process of making gametes there will be a wrong number of chromosomes/ when it turns into a zygote and undergoes mitosis it will duplicate with a wrong number of chromosomes
