What is the reason that closely linked genes are typically inherited together? the likelihood of a crossover event between these two genes is low. All female mammals have one active X chromosome per cell instead of two. What causes this?l the basic rules of inheritance were first demonstrated by Gregor Mendel in the mid-1800s. l at the time of Mendel's work, most thought that parental traits were fluids that "blend" • Two of the F1 plants from before are crossed. What are the expected ratios of phenotypes and genotypes in the F2 generation?Within each cell, genes are located on chromosomes. About chromosomesChromosomes are the Genes are in the DNA of each cell in your body. They control how the cell functions, including You inherit one set from your mother and one from your father. One chromosome in each set determines...A) chromosomes are unbreakable B) the number of genes in a cell is greater than the number of chromosomes.What is the reason that closely linked genes are typically inherited together? One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this alteration called?

Linked genes will tend to be inherited together and hence don't follow normal Mendelian inheritance for a dihybrid cross. Instead the phenotypic ratio will be more closely aligned to a monohybrid cross as the two genes are inherited as a single unit. Linked genes may become separated via...Changes in genes can cause a wide range of conditions. Sometimes a changed gene is inherited, which means it The genes are like a series of letters strung along each edge. These letters are used like an instruction book. Humans typically have 46 chromosomes in each cell of their body, made...Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.4. The largest development in the debate among scientists about what killed the prehistoric dinosaurs is the idea that acid rain was the cause. Some geologists suggest that a large meteor hitting the earth at the speed of 65 kilometres per second was able to lead to strongly acidic rain falling all over the world.

Observation A judgement or decision reached by reasoning. Results. The action or process of discovering or being discovered. In science, something is a fact or a law if it conforms to all the results we have at any time, but history shows us that what is (10) … as fact or as a law in one...D. Genes align that way during metaphase I of meiosis. E. Alleles are paired together during meiosis. The problem is partly in the language, which I admit we sometimes get sloppy with, but to be specific: linked genes are inherited together, however alleles of the same gene cannot be linked...A dominant gene can be expressed even if only one copy of the gene is present. A recessive trait will only be expressed if an individual has two recessive alleles.The genes you inherit do not necessarily determine what you will look like, or your personality. Genes and the environment work closely together to create your phenotype. The predisposition for all traits is genetic, although actual expression of genes is the result of environmental exposure.Alleles Are Paired Together During Meiosis. Chromosomes Are Unbreakable. Genes Align That Way During Metaphase Group of answer choices. The likelihood of a crossover event between these two genes is low. The number of genes in a cell is greater than the number of chromosomes.

B. They are positioned close together on the similar chromosome

The problem is partially in the language, which I admit we once in a while get sloppy with, however to be specific: linked genes are inherited together, on the other hand alleles of the same gene can't be linked because alleles are kinds of a gene, however alleles of *different* genes *can* be linked.

Think of yourself conserving two sticks. One stick has an "A" marked on it and in addition has a "B" marked on it. The other stick has an "a" marked on it in the same position as the A on the other stick and a "b" marked on it in the same place as the B on the different stick. Now, throw one stick against one nook of the room and the other stick in opposition to the other nook (you could have essentially just executed Anaphase I of meiosis, simply think that each and every stick was once if truth be told a doubled chromosome with two chromatids). Notice that the A and B genes went to at least one facet of the room and the a and b genes went to the other facet of the room. These genes had been linked: A with B and on the other stick, a with b on the other stick. So, if the oldsters were AB and ab, then the offspring will even receive a chromosome stick from one corner of the room, either the keep on with AB or the stick to ab. Notice that the A and B genes are both on the same chromosome (stick).

If the genes have been unlinked (genes on other chromosomes), then you might have two sticks (let's say colored blue) one with an "A" on it and the other with a "a" on it and some other two sticks (let's assume coloured inexperienced) with a "B" on one and a "b" on the different. So, if you happen to throw considered one of each blue persist with the every corner of the room and one among every green persist with each and every nook of the room, then in every nook you'll have a blue stick and a inexperienced stick. In one corner, you'll be able to have an A on a blue stick and a B on a green stick and in the different corner you'll be able to have an A on a blue stick and a b on a green stick. These genes are unlinked (on other chromosomes).

Hope this helps a little.
