How can you predict the outcome of a genetic cross?
The outcome of a genetic cross can be predicted using Punnett squares, which show all possible allele combinations from the parents and the likelihood of those combinations in the offspring. By understanding the genetic makeup of the parents and the process of genetic inheritance, researchers can determine the probabilities of different traits appearing in the offspring.
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.
What is an fixed allele APEX?
an allele present in all members of a population- APEX
How many different kinds of gametes can a DdGgww individual form?
A DdGgww individual can form 4 different kinds of gametes. This is because during gamete formation, each allele pair segregates independently of the other pairs, following the principle of independent assortment.
What is a fixed allele.?
An allele present in all members of a population

How do you determine the possible gametes in a dihybrid cross?
Using a punnett square - you write the possible gamete combinations of one parent across the top and those of the other down the side.By filling in the square, you determine all the possible allele combinations of the offspring.XRDRdrDrdRDRRDDRRDdRrDDRrDdRdRRDdRRddRrDdRrddrDRrDDRrDdrrDDrrDdrdRrDdRrddrrDdrrdd
What is a chart that shows all possible allele combination resulting from a genetic cross?
A Punnett square is a diagram used to predict the possible genotypes of offspring in a genetic cross. It displays all possible combinations of alleles that parents can pass on to their offspring.
What are all the possible allele combination that could be formed if this cell undergoes meiosis?
During meiosis, the possible allele combinations that could be formed depend on the number of alleles present for each gene. If the cell is diploid (2n), then there are 2^(n) possible combinations, where n is the number of alleles for each gene. For example, with two alleles (A and B) for a single gene, the possible combinations are: AB, Ab, aB, and ab.
Can a rh positive father have a rhs negative baby?
Yes, it is possible. There are two genetic alleles that together determine whether a person is Rh positive or negative. It is the combination of these alleles within the parents that determine the child's Rh status. In this case, both mother and father are positive so their alleles can only be ++ or +-. The possible combinations are determined by taking one allele from one parent and combining it with an allele of the other until all combinations are made. Positive is the dominant allele so combinations of ++ and +- are considered Rh positive whereas -- combinations are negative. The possible combinations are: ++ which would be an Rh positive baby +- which would be an Rh positive baby -- which would be an Rh negative baby So yes, it is possible.
How to find possible genetic combinations given a genotype?
To find possible genetic combinations from a genotype, you can use a Punnett square. Place the alleles from one parent along one side and the alleles from the other parent along the other side. Then fill in the square to determine all possible allele combinations that could be inherited by the offspring.
What shows all of the possible outcomes of a genetic cross?
A Punnett square shows all of the possible outcomes of a genetic cross. It is a grid that illustrates the combinations of alleles from each parent, allowing for the prediction of offspring genotypes and phenotypes. By filling in the squares with the potential allele combinations, one can visualize the likelihood of each outcome resulting from the cross.
Dominance exists in all allele combinations?
Although not all combinations have a dominant allele, dominance does play a role in determining the phenotype when present. In some cases, both alleles may be expressed equally or result in a unique trait differing from the dominant alleles. It's essential to consider the influence of both dominant and recessive alleles in genetic inheritance.
What are all of the combinations of 10?

What is Di-allele?
An allele is one of the possible forms of a gene. Most genes have two alleles, a dominant allele and a recessive allele. If an organism is heterozygous for that trait, or possesses one of each allele, then the dominant trait is expressed.DI/Di alleles (ISBT 010) Blood Group Alleles refers to the Diego blood groups and variations on this set of several alleles (approximately 25 of them) can affect the shape of RBCs (red blood cells). Most of the Di has 3 variations Di(a+b-), Di(a-b+) and Di(a-b-). Di(a-b-) is a Null Phenotype which means fails to produce normal gene function.
How can you predict the outcome of a genetic cross?
The outcome of a genetic cross can be predicted using Punnett squares, which show all possible allele combinations from the parents and the likelihood of those combinations in the offspring. By understanding the genetic makeup of the parents and the process of genetic inheritance, researchers can determine the probabilities of different traits appearing in the offspring.
