Answer:

Chromosomes are a microscopic thread-like structure, and it is the part of a cell that carries hereditary information in the form of genes.

Homologous chromosomes the relationship between two chromosome, consists of the same gene sequence, each derived from one parent. They consist of alleles of the same type of genes in the same loci. Homologous chromosomes pair up during the process of meiosis 1. The part of the Homologous chromosomes can be exchanged during the process of recombination. Examples of these are 22 autosomal chromosomes in humans.

Non-homologous chromosomes do not belong to the same pair, they consist of alleles of different types. Non-homologous chromosomes do not pair up during the process of meiosis 1. The part of the Non-homologous chromosomes can be exchanged during the process of translocation. Examples are X and Y chromosomes.

Lady bird [3.3K]

Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses
