How would you be able to tell if two chromosomes were homologous?
|
|
Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during anaphase I, within which the chromosomes share genetic information (DNA).

|
Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during metaphase I, within which the chromosomes share genetic information (DNA).
|
|
|
Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during prophase I, within which the chromosomes share genetic information (DNA).
|
|
|
Homologous chromosomes are chromosomes that are the same. These chromosomes cross-over during prophase II, within which the chromosomes share genetic information (DNA).

Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles. Some of the variants in these alleles might have functional implications while others will not.
Detailed explanation-3: -After crossing-over occurs, the homologous chromosomes separate to form two daughter cells.
