Why are predicted ratios rarely the same as actual ratios?
They Are Rarely The Same Because With Predicted Ratios Its Just A Guess But With A Actual Ratio You Have Accurate Answers .
Is it possible that two prokaryotic organisms show phenotypic similarities but do not share close evolutionary relatedness?
It is possible that two prokaryotic organisms may look alike, phenotypic similarities, but still have major genetic differences, genotypic dissimilarities, that would indicate that they are not closely related. For example if two prokaryotic organisms share 97% of their rRNA gene sequence then they are considered to have the probability of being in the same species. However, even if two prokaryotic organisms share less than 95% of their gene sequence then they will be considered a new species and therefore they would not be related even if 95% of their gene sequences match therefore not sharing close evolutionary relatedness.
What is true breeding?
Purebred organisms are the organisms in the off springs for many generations which have the same traitA true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring.
Why do traits that are controlled by genes on the same chromosome not always appear in the expected ratio in offspring?
I think this has something to do with "crossing over," but I do not remember the details. All I remember is that the allelle of one chromosome may overlap and switch with the allelle of another chromosome, which results in unexpected ratios of the genotypes and phenotypes of traits represented by genes that would normally be found on the same chromosome.
Is is true that bones always stay the same size?
No. Bones are always changing, but the length usually stays the same all your adult life.
What are the ratios that name the same comparison?
equivalent ratios are different ratios that name the same comparison
Do compounds usually have variable ratios where as mixtures usually have fixed ratios?
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
What are equivlent ratios?
when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios
What are ratios that have same value?
Equivalent ratios.
What are ratios that name the same amount?
your answer simular ratios
What is equivalent ratios mean?
ratios that r the same
What is two ratios that the same value?
Equivalent Ratios
When two ratios have the same value?
When they are equivalent ratios.
What would be the offspring be if a roan cow and a white bull were bred together?
The offspring produced is dependent on chances. We can figure out the chances of the kind of offspring such a cross will get by using a Punnett square. Unfortunately the WYSIWYG format on this site will not allow for such a square, so we will give the ratio, the genotypic and phenotypic percentages that such a cross will receive. Let R = red, W = white and RW = roan. Roan cow (RW) x White bull (WW) Offspring: 2 RW : 2 WW Genotypic ratio: 50% roan and 50% white Phenotypic ratio: Same as above. Thus, the offspring of a roan cow crossed with a white bull (presumably of the same breed, being Shorthorn), may come out as white or roan. There is a 50% chance that either will occur.
What are ratios that are equal and simplify to the same ratio?
They are equivalent ratios.

What are equivilent ratios?
Two ratios are equivalent if their simplest forms are the same.
