In a reciprocal translocation, two different chromosomes have exchanged segments with each other. In a Robertsonian translocation, an entire chromosome attaches to another at the centromere.
What is non reciprocal translocation?
What is a Nonreciprocal Translocation. Nonreciprocal translocation is a type of chromosomal translocation that results from the movement of a segment of a chromosome from one location of a nonhomologous chromosome to another. Therefore, it is a one-way transfer of genes from one locus of the genome to another.
How is a Robertsonian translocation different from a reciprocal translocation quizlet?
How is a Robertsonian translocation different from a reciprocal translocation? Robertsonian translocations occur between whole acrocentric chromosomes, and reciprocal translocations occur between any two nonhomologous chromosomes.
What do you mean by Robertsonian translocation?
Robertsonian translocation is the most common form of chromosomal translocation in humans. It means that two chromosomes, the structures that make up a person’s DNA, join together in an abnormal way.
What causes a Robertsonian translocation?
A Robertsonian translocation results when the long arms of two acrocentric chromosomes fuse at the centromere and the two short arms are lost. If, for example, the long arms of chromosomes 13 and 14 fuse, no significant genetic material is lost—and the person is completely normal in spite of the translocation.
How many chromosomes does a person with Robertsonian translocation have?
45 chromosomes
Can I get pregnant with a balanced translocation?
Natural conception and live birth is possible in cases of balanced translocation, but those with the condition may have more difficulty conceiving and are at a greater risk of recurrent miscarriage than those without it.
How does translocation affect offspring?
Individuals who carry a balanced translocation are at risk of having recurrent miscarriages or indeed a child with congenital abnormalities and/or learning difficulties as the offspring might inherit an unbalanced form of the translocation.
What is the usual effect of a Robertsonian translocation?
What is the usual effect of a Robertsonian translocation? Chromosome number is increased by one.
How is Robertsonian translocation detected?
Robertsonian translocation type trisomy 13 can be detected by prenatal diagnosis technology, which inclue molecular cytogenetics and traditional karyotype analysis. Different diagnosis technologies have to be clearly distinguished and correctly applied.
Which type of chromosomal mutation causes Klinefelter syndrome?
Causes of Klinefelter syndrome Klinefelter syndrome is caused by an additional X chromosome. This chromosome carries extra copies of genes, which interfere with the development of the testicles and mean they produce less testosterone (male sex hormone) than usual.
