What is the relationships between chromosomes and homologous chromosomes?
Chromosomes refer to structures with DNA and proteins that contain genetic information. The term "homologous chromosomes" is used to specify that the chromosomes contain the same genes, but have the same or different alleles.
Are homozygous and homologous the same?
Homologous: pair of chromosomes that are the same Homozygous: alleles of a gene pair are the same
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.
Homologous chromosomes are similar in all of these characteristics EXCEPT?
carry the same alleles for all traits
Does cytokinesis provide new genetic combinations?
Yes. Crossing over (or recombination) shuffles sequences between homologous chromosomes. The resulting chromosomes have different combinations of alleles from the original chromosomes.
Different alleles of the same gene are found?
at the same place on homologous chromosomes source: Alleles of a gene reside at the same locus on homologous chromosomes.
What is the relationships between chromosomes and homologous chromosomes?
Chromosomes refer to structures with DNA and proteins that contain genetic information. The term "homologous chromosomes" is used to specify that the chromosomes contain the same genes, but have the same or different alleles.
What kind of alleles for a gene are carried on homologous chromosomes?
The kind of alleles for a gene that are carried on homologous chromosomes are many. These are for similar genes which may be slightly different like the eyes, hairline, dentures and so much more.
Suppose that two alleles on one homologous chromosome are A and B and the other homologous chromosomes's alleles are a and b How many different genetic types of gametes would be produced without cro?

1Normal human lung cells contain two copies of chromosome 3 Together these are called a pair of homologous chromosomes How are homologous chromosomes similar and how are they different from one ano?
Homologous chromosomes have all the same genes however they may have different alleles (versions) of those genes.
Are homozygous and homologous the same?
Homologous: pair of chromosomes that are the same Homozygous: alleles of a gene pair are the same
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 does it means to have homologous chromosomes?
the gene's alleles are found in matched chromosome pairs
What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
What are homologous choromosomes?
Homologous chromosomes are pairs of each other. They are chromosomes that are identical to each other except for a few variations. Everybody has one from their mom and dad. Everybody has 46 chromosomes, but in reality it is less confusing to say "we have 23 pairs of chromosomes."
Do homologous chromosomes always have identical alleles?
no they don't necessarily have to have the same alleles but they have the same genes. Homozygous chromosomes would have the same allele for a particular gene and heterozygous chromosomes would have different alleles for a particular gene.
What is hmozygous?
A cell is said to be homozygous for a particular gene when identical alleles of the gene are present on both homologous chromosomes. For example, if the alleles are AA or aa the cell is homologous for that trait. It is heterozygous if it is Aa
