What type of diagnosis is from a karyotype?

A karyotype tells you if you have the normal ammont of chromosomes (46 for humans), it can also tell you if you have more or less and if this is the case what it is that you have. The most common syndrome would be Down Syndrome, or trisomy 21. Down Syndrome is also called trisomy 21 because if you look at a karyotype from someone that has this syndrome then they have three coppies of the 21st chromosome.


What type of picture would a biologist look at to determine whether a fetus has Down syndrome?

a Karyotype


What would the karyotype look like for a male where would the chromosome be?

A male's karyotype typically consists of 22 pairs of autosomal chromosomes and one pair of sex chromosomes, XY. The chromosomes would be arranged from largest to smallest, with the sex chromosomes at the end. So, the karyotype for a male would show 46 chromosomes, arranged with the XY sex chromosomes in the 23rd pair.


Will a karyotype of a 14 year old look different from a 60 year old?

yes


Can a karyotype determine eye color?

A karyotype is chart that shows all the chormosomes paired up and in order. A karyotype cannot determine eye color but it can determine what colors that specific person carries and can pass down to the next generation. BUT to determine what the next generation eye color will look like, it is not possible yet, but you can do a punnett square and that will show you the possible choice(s).

Will the karyotype of a 14 year old look different from that of a 60 year old?

Absolutely not, karyotype is not affected by age. The spread of a 14 yr old's chromosomal DNA will look exactly the same as a 60 yr old's to the naked eye unless certain diseases are present.

Can a genetic counselor use a karyotype to identify a carrier of cystic fibrosis why?

No, a karyotype looks at the physical structure of the chromosomes. Cystic fibrosis is caused by mutations in the CFTR gene. Karyotypes cannot identify a mutation at the base pair level, only large deletions, duplications, rearrangements of the chromosomes. It would be comparable to trying to use a magnifying glass to look at electrons.


How should a human karyotype look like?

A human karyotype typically consists of 22 pairs of autosomes and one pair of sex chromosomes (XX for females, XY for males), totaling 46 chromosomes. The chromosomes should be arranged in size order, with the sex chromosomes typically shown separately. Abnormalities in chromosome number or structure can lead to genetic disorders.
