How are genes genomes and chromosomes related?
Chromosomes are strans of DNA genes are what chromosomes are made up of. A gene can be dominant or recessive and that is why one of you parents has brown eyes and the other has blue and you have brown because brown eyes is dominant and blue is recessive. Hope this helps
Why are even closely related siblings often different both in genotype and phenotype?
because chromosomes exchange genes before forming in eggs and sperms.
Does meiosis have an interphase where chromosomes are replicated?
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
Who was Gregor Mendel and what contributions did he make?
Gregor Mendel (1822 to 1884) was an Austrian monk. He is often called the "father of genetics." Mendel and Walter Sutton's (an American scientist who lived from 1877 to 1916) work is related. Here is why: Mendel developed the basic laws of how traits are passed on to offspring. He did not know about genes, chromosomes, DNA, or meiosis. That's when Sutton found out that chromosomes contained genes, and had discovered Mendel's units of heredity! The laws stated below combine the work of Mendel and Sutton.Individual units called genes determine an organism's traits.A gene is a segment of DNA, located on the chromosomes, that carries hereditary instructions from parent to offspring.For each gene, an organism typically receives one allele from each parent.If an organism inherits different alleles for a trait, one allele may be dominant over the other.The alleles of a gene separate from each other when sex cells are formed during meiosis.
What are regions of the chromosome with few functional genes called?
Regions of the chromosome with few functional genes are called gene deserts or gene-poor regions. These regions typically have a lower density of genes compared to other parts of the chromosome, and are often associated with non-coding DNA or regulatory elements.

DNA is often tightly wound into structures called?
DNA is located in chromosomes inside the nucleus of a cell. This is called nuclear DNA. An organism's complete set of nuclear DNA is called its genome. Humans have a small amount of DNA found in structures mitochondria, which generates the energy the cell needs to function properly.
Genes that encode for drug resistance and can be shared between bacteria are often found on?
plasmid
Does meiosis have an interphase where chromosomes are replicated?
Yes - interphase includes a synthesis stage (often called the 'S phase'), which comes after G1 and before G2. This is when the chromosomes are replicated.
What is cell division controlled by?
Genes called proto-oncogenes stop a cell from dividing too often.
What is controls cell division?
Genes called proto-oncogenes stop a cell from dividing too often.

What controls the transcription of prokaryotic genes?
The operon often controls the transcription of prokaryote genes.
In what part of the cell is chromosome 7 found?
That depends entirely on the species.First of all, chromosomal arrangements are different per species. Bananas have an entirely different set of chromosomes than us apes. We both have a chromosome numbered 'chromosome 7', but they're different chromosomes (although we do share many of the same genes).As to the part of the cell where chromosomes may be found; that too differs from one organism to the other. Humans, bananas, spiders and algae all belong to the domain of Eukaryota, which is characterized by the fact that its genetic material is confined to the cell nucleus, wrapped in an internal membrane. In bacteria and archaea, part of the domain of Prokaryota, the chromosomes (or chromosome: archaea often have one single circular chromosome) float freely in the cell.
These animals often called cows are found in ranching areas?
Female bison, female buffalo, and female bovines are often called cows and are found in ranching areas.
