Answer:
The recombination frequency between two genes can not be more than 50 percent due to the independent and random assorting of the genes that are linked generating 50% recombination.
* Genes should be located far enough from one another so that crossover points can be made.
Example: Genes present at the 2 extreme ends of the chromosome.
* There should not be the linkage between the two genes due to linked genes go together. So no recombination happens.
It may be more than 50% if selected parents are heterozygous. But Mendel took homozygous parents. So, the maximum is 50%. There will be no recombinant if the two genes are linked.
Answer:
Muscle Tissue : The kidneys rely on blood pressure to move, since they lack muscle tissue.
Epithelial Tissue : The kidneys contain simple cuboidal epithelial tissue, which secretes and absorbs. Thus absorbing toxins from blood to be turned to urine.
Nervous Tissue : Kidneys to not contain nervous tissue due to the fact that they do not control when you urinate, but rather simply just pass the urine to the bladder.
Connective Tissue : Kidneys do contain Connective Tissue, called renal fascia, in order to keep the many elastic tubes in place, and a capsule of renal fascia closely envelopes each kidney to protect, and provide support for each kidney inside.
