∙ 12y agoThe value of studying genetics is in understanding how we can predict the likelihood of inheriting particular traits. This can help plant and animal breeders in developing varieties that have more desirable qualities. It can also help people explain and predict patterns of inheritance in family lines.
One of the easiest ways to calculate the mathematical probability of inheriting a specific trait was invented by an early 20th century English geneticist named Reginald Punnett . His technique employs what we now call a Punnett square. This is a simple graphical way of discovering all of the potential combinations of genotypes that can occur in children, given the genotypes of their parents. It also shows us the odds of each of the offspring genotypes occurring.
Setting up and using a Punnett square is quite simple once you understand how it works. You begin by drawing a grid of perpendicular lines:

Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called?
Traits that typically will only be expressed in offspring if they inherit two copies of the genes for the trait are called Recessive traits. - Nikkkki
When a recessive gene is inherited from only one parent and a normal gene is inherited from the other parent will the offspring have the condition?
A recessive trait shows up when there is no dominant trait to mask it. For example, say the allele for brown hair is B and for red hair is b. If the father contributes an allele for brown hair and the mother contributes and allele for red hair, the child's phenotype would be Bb and it would have brown hair. However if both parents contributed an allele for red hair, the child's phenotype would be bb and it would have red hair. You can do the same thing for eye color. Say the allele for green eyes is G and the allele for blue eyes is g (I don't know if this is actually correct, but it's just an example). If the father gives the allele for green eyes, G, and the mother gives the allele for blue eyes, g, the child's phenotype is Gg and it has green eyes. However, if both parents contribute alleles for blue eyes, then the child's phenotype is gg and it has blue eyes.
What is the probability that a pregnancy will abort if the mother and father both carry a lethal recessive allele?
If both parents carry the trait then there is a only a 25 percent chance the pregnancy will abort but there is a 75 percent chance the child will carry the trait and that can cause abnormalities during the pregnancy and afterwards.
How many alleles for one trait can an individual have?
Genotypes consist of two alleles for every trait. You inherit one allele from one parent, and another from the other parent.
What is the puntt square used for?
The punnett square is used to determine the probability of an offspring inheriting a trait from it's parents.
What is the probability that a parent carrying a dominant trait will pass that trait on to each child?
The probability that a parent carrying a dominant trait will pass that trait on is a 50% chance with each pregnancy
What is the probability Two individuals with autosomal recessive trait will have a child with the same trait?
If they are expressing the trait, 100%, as their genotypes would be, rr X rr If they both carry the trait and it is dominated, Rr X Rr, then the probability would be, 25% of their child expressing the trait.
Will an offspring show a recessive trait if only one of its parent has the gene for that trait?
A family tree is a great idea, but the science is based on probability. The probability that a recessive trait will show up in a family is 25% if both parents are carriers. In order for a recessive trait to show up in a person, he/she must inherit a copy of the recessive trait from both parents. If one parent is recessive, let's say "rr" and the other parent is a carrier, say "Rr", the probability is 50%. If both parents are recessive, the probability is 100% (rr x rr). If neither parent carries the trait the probability is 0% (RR x RR). BUT, this only tells you what MIGHT happen. We all know that the probability of having a boy is 50:50, but we all know families of all boys. So it would be interesting to see if the probability works out in your family. If you do a search on the web for "genetics" or "probability and genetics" you will get plenty of hits. vanhoeck
How do scientist predict which genes an organism will inherit?
The scientist will produce a pedigree from information about the members of past and present generations, and will use that information to predict the probability that an offspring will inherit a specific (usually undesirable) trait.
How can offspring inherit a recessive trait?
An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.
I have hb e trait my wife has hb d trait If I have a child what is the probability of the child getting thalassemia My first child does not have thalassemia?
you have a 50/50 chance me and my twin both had it and my 2 older brothers are fine 1 is a carrier and the other is not.
Are recessive traits inherited?
A recessive trait can only be passed along if both parents carry at least one of the recessive genes to the child. If both parents manifest the trait (that is, if both parents have both recessive genes), then the child will manifest (that is, carry both recessive genes and display) the recessive trait. If one parent manifests and the other parent only carries the trait (that is, carries one dominant and one recessive gene) then the child will definitely carry and have a 50% chance of manifesting. If both parents carry the recessive, the child is 25% likely not to carry the trait at all, 50% likely to carry and 25% likely to manifest the trait.
Where the alleles for a given trait are inherit from?
The alleles for a given trait are inherited from an individual's parents.
An example of a trait you inherit from your parents is?
Eye color.

What controls the trait children inherit?
