What does it mean when chromosomes are homologous?
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations. However, they don’t necessarily have the same versions of genes.
What is an analogous chromosome?
As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.
Is Klinefelter syndrome dominant or recessive?
FGF8) account for only 25%-35% of cases. Female individuals with an autosomal dominant or recessive form can also be affected, whereas Klinefelter syndrome occurs only in male patients.
Are homologous chromosomes the same as homologous pairs?
Explanation: Although both are very similar, the difference between the two is the pairing. Homologous chromosomes are basically two similar chromosomes inherited from father and mother.
Which of the following best describes a homologous chromosome?
Which of the following statements best describes homologous chromosomes? Chromosomes that have the same genes in the same position and are the same size and shape.
Whats the difference between homologous and analogous?
Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale’s front flipper are homologous to the bones in the human arm. Some structures are both analogous and homologous: bird and bat wings are both homologous and analogous.
Which parent is responsible for Klinefelter’s syndrome?
Klinefelter syndrome is not caused by anything the parents did or did not do. The disorder is a random error in cell division that happens when a parent’s reproductive cells are being formed.
Which characteristic is commonly associated with Klinefelter syndrome?
Taller than average stature. Longer legs, shorter torso and broader hips compared with other boys. Absent, delayed or incomplete puberty. After puberty, less muscle and less facial and body hair compared with other teens.
