No, chromosomes are made of genes and DNA. Gene sequences make up DNA, and this DNA is coiled up and makes up chromosomes.

Genes found on the x and y chromosomes are often called?
sex-linked genes
What describes corresponding chromosomes?
Corresponding chromosomes refer to a pair of chromosomes in which one chromosome is inherited from the mother and the other from the father. They have the same genes at the same positions, known as loci, but may have different alleles for those genes. Corresponding chromosomes are also known as homologous chromosomes.
What do x y chromosomes affect?
Whether someone is a female or male.
In the cell of a sexually reproducing organsim a pair of similar chromosomes with the same genes in the same locations is known as?
the answer is homologos
In the cell of a sexually reproducing organism a pair of similar chromosomes with the same genes in the same locations is known as a?
homologous

What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
What do x y chromosomes affect?
Whether someone is a female or male.
DNA molecules that can replicate independently of the main chromosomes of bacteria known as?
Plasmids

homologous
Where do alleles come from?
Alleles come from other genes through a process known as mutation. They are found on the same place on the chromosomes.
In the cell of a sexually-reproducing organism a pair of similar chromosomes with the same genes in the same locations is known as a pair?
homologous
Why does the frequency of cross-overs give information about the relative locations of genes?
its simple the crossing over of genes ha a location looc for a chromosomes with a different chromatid you have the location
Why does genetic deversity result in miosis one?
In prophase I there is a phenomenon known as genetic recombination or crossing over. Similar or homologous chromosomes get together to form a structure known as a tetrad. Two chromosomes (of the four= tetra) are originally from the parental sperm and the other two chromosomes are from the maternal source. Exchanging the DNA from one chromosome to another mixes the genes on these chromosomes so that after crossing over each chromosome is a mixture of maternal and paternal genes.
In plants and animals an offspring inherits How Many genes?
The number of genes and number of chromosomes inherited depend on the species. The number of chromosomes a species has is known as the chromosome number. For example, (disregarding polyploidy or polysomy) a human baby has 46 chromosomes, but a horse has 64. Chromosomes usually occur as one of a pair in humans, and so they have 23 pairs of chromosomes. However, it is common in plants to have many sets of chromosomes and so they do not occur in pairs, but in triplets, or as sets of 4, 5 or 6 etc. Some species of strawberries have 7 of each chromosome. The number of genes depends on how long the chromosome is, and each chromosome in each different species will have a different number of genes on the chromosome.
