Two short haired guinea pigs are mated several times out of 100 offspring 25 of them have long hair what are the probable genotypes of the parents?
It's obvious from this problem that short hair is dominant in guinea pigs. In that case, if we have 25 out of 100 offspring that have long hair, then there is no doubt that the parents are heterozygous for short hair. If you use the punnet square, and hypothesize that both parents are heterozygous for short hair and long hair, you will get a 25% chance that the offspring will be long haired.
So, the answer to this problem is that both parents are heterozygous. Let H = short hair and h = long hair.
Hh dam x Hh sire gives us, according to the Punnet Square:
25% HH
50% Hh
25% hh

Shows the inheritance of a particular trait over several generations?
Inheritance of a particular trait over several generations can be displayed using a Punnett square to predict the possible outcomes. By following the principles of Mendelian genetics, one can determine the probability of offspring inheriting the trait based on the genotypes of the parents. Observing how the trait is expressed in each generation helps track its inheritance pattern.
What a ratio?
A genotypic -ratio reflects the genetic configuration of an individual in the population. Several genotypes are possible in a phenotype and the ratio in which the genotypes segregate in a given phenotype is known as its genotypic ratio.
How long after birth do parents care for offspring?
Humans take care of their offspring generally till they are 18. But in some cultures it's as soon as they can marry them off, or they never stop fully taking care of the offspring till the parent themselves die.
Who predicted that the existence of several missing elements?
You think probable to Dimitri Mendeleev.
How Come parents cannot give blood to their offspring automatically?
Because there are several different blood types, and they can only be mixed in certain ways. And since the blood type isn't inherited straight off, parents aren't automatically a good match for their kids.
Was Athena the only girl in her family?
There were several offspring of Zeus that were female.
Can sickle cell trait skip a generation?
yes it can skip a generation, since it is a Mendel inheritance. and it is a reccesive trait. therefore offspring's can have two unaffected parents but chances are both parents might be carriers
What is pure breeding in genetics?
Pure breeding in genetics refers to a process where organisms with homozygous genotypes for a particular trait are consistently bred over several generations to produce offspring that also have the same homozygous genotype. This results in offspring that consistently exhibit the same phenotype for the specific trait.
A person with phenotype A blood has how many possible genotypes?
Although there are actually several genes which determine ABO-type, they are usually placed into the three basic groups i.e. A, B and O.For each phenotype, the genotypes follow:O: OO is the only possibility.A: AA or AO are both acceptable.B: BB or BO are both acceptable.AB: AB is the only possibility.

You think probable to chemical weapons.
