Did Mendel find all the 7 traits on 7 different chromosome?
Gregor Mendel studied seven different traits in pea plants, but these traits were not necessarily found on seven distinct chromosomes. Instead, each trait is controlled by genes located on different chromosomes, and the principles of Mendelian genetics apply to the inheritance of these traits independently of their chromosomal location.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
The fact that all seven of the pea plant traits studied by Mendel obeyed the principle of independent assortment means that?
the genes for those traits are located on different chromosomes or are far apart on the same chromosome. This allows for the random distribution of alleles during meiosis, leading to a wide variety of trait combinations in offspring.
All of the genes located on a given chromosome comprise a?
linkage group
Made up of DNA and are located on the chromosomes?
Chromosome 5

Are all traits of an organism found in its gene?
yes each gene has 100 chromosome on it

ARe all Y-linked traits holandric?
No, not all Y-linked traits are holandric. Holandric traits specifically refer to traits that are carried on the Y chromosome and passed from father to son. While all holandric traits are Y-linked, the reverse is not necessarily true. Some Y-linked traits may not exhibit holandric inheritance patterns.

Are all sex genes in male and female located on the sex chromosome?
No, the sex chromosome will just activate them, for instance, masculine characteristics may be on chromosome 3, the y chromosome will activate these in a man and a second x chromosome will deactivate these in a woman.
All of the genes located on a given chromosome comprise a?
linkage group
X-linked traits carried by father will be passed on to who?
X-linked traits carried by the father will be passed on to his daughters. Sons will inherit their X chromosome from their mother and their Y chromosome from their father, so they will not inherit X-linked traits from their father.
Made up of DNA and are located on the chromosomes?
Chromosome 5
Does the inheritance of one trait effect the inheritance of another trait?
The inheritance of one trait does not directly affect the inheritance of another trait, as different traits are usually controlled by different genes. However, traits located on the same chromosome may be inherited together due to genetic linkage.
All of the genes located on a given chromosome comprise a a karyotype b bridging cross c wild-type allele d linkage group e none of these?
linkage group, which is all the genes on a chromosome. linkage group, which is all the genes on a chromosome.
Why sex-linked traits follow different patterns of inheritance than other traits?
Sexlinked traits follow a different pattern of inheritance than a non-sex linked trait because of the size difference between the X and y chromosomes. Think about non-sex chormosomes as being the same size, each having the exact same number of genes in the same postions (loci). This means that a person has to have two copies of the recessive genes (one on each homolog of that chromosome) before the trait will be expressed. Lets say A is normal (dominant) and a is abnormal (recessive). People who are aa have the abnormal condition and people who are AA or Aa are normal. The normal ratio is 1 AA:2 Aa:1 aa if both parents are Aa. There is a 25% chance that a child will inherit two abnormal genes and the chance of any sex child will be so affected is exactly the same. When a recessive trait is located on the X chromosome only a female with two X chromosomes has the same number of genes on each X chromosome (the two X chromosomes have the same inheritance behavior as a homolog chromosome in females). In males who inherit the much smaller y chromosome there are many genes on the X chromosome that do not have a matching gene on the y chromosome. This means that recessive traits on the X chromosome that have no matching genetic material on the y chromosome will always be expressed. So, lets say that there is a family where the mother is Aa and the father (who only has one allele on the y chromosome is A. (A is normal and a is abnormal). None of the daughters produced can be aa, because the father will always pass A. Daughters will only be Aa or AA. Sons on the other hand, will get either A or a from the mother and, since the y chromosome has no genetic material at this gene locus the boys will be A normal or a affected at in a 1:1 ratio. If the father is a on his X chromosome, and the mother is AA 100% of the daughters will be carriers (Aa) and all the sons will be normal (A-).
