When performing a DNA test to establish maternity do all the alleles have to match?

No, because some of the alleles will match the father; however, all of the alleles must either match one of the mother's alleles or one of the father's alleles.

How do the events in the cell cycle ensure that the genetic information in daughter cells will be identical to that of the parent cell?
the alleles have to match up .
How can DNA tell if 2 humans are brother and sister?
A basic DNA kinship test can be done, which compares two people on a small set of autosomal genetic markers, called alleles. An allele is a form of a DNA sequence of a particular gene. A person inherits alleles randomly from both parents. Basically, by testing to see how many alleles two people share in common, a conclusion of high or low probablity of relatedness can be drawn. Some values are more common to match with people, while others are not. The rarer the alleles that match up, the more likely a person is related to the comparison. Therefore, if you share a lot of rare alleles with a person, there is a high probability you two are related.
What is the only evolutionary mechanism that consistently leads to adaptive evolution?
Natural selectionBecause natural selection has a "sorting" effect, it consistently increases the frequency of alleles that improve the match between an organism and its environment.
What happens when a population is in hardy wienberg equilibrium?
Allele frequency is stable The phenotype frequency does not change.
What is the difference between homozygous and heterozygous?
Heterozygous is when the organism has two different alleles for a traitHomozygous is when they have two of the same the sameexample of homozygous= two blue eyesexample of heterozygous= one blue eye and one green eyeHomozygous is when the combination of alleles are the same. EX: AA or BB. Heterozygous are when the combination of alleles are different. EX: Aa or Bb.
Can you give a sentence with the word performing?
The team were performing well in the first half of the match.

How do you derive the proper gametes when working a genetic problem?
Make a punnet square with the alleles aligned on both sides and match up the results.

How do you match equivalent fractions?
One way to do it is to convert them to decimals by performing the division. Equivalent fractions become the same decimal.
When did Wales rugby team establish?
Wales' first International Rugby Union match was played on February 19th 1881.
How is class 1 mhc involved in organ donation situations or bone marrow transfer?
MHC class 1 receptors have different genes encoding it: HLA-A, HLA-B and HLA-C. Each gene come in two versions, mom and dad, so that is a total of 6 possibilities. MHC is highly polygenic and polymorphic. HLA-A has 59 alleles, HLA-B has 111 alleles and HLA-C has 37 alleles. 59*111*37*6*2 = ~3 million combination. The odds that you will exactly match the same alleles as a donor is almost none. So they try to match several of the most important ones and even then it is very difficult. If your MHC's don't match well the organ receiver's adaptive immunity (specifically T cells) will recognize the transplanted organ as foreign and reject it.
Why did the Spartans won in the peloponnesian?
Persia gave the Spartan-led Peloponnesian alliance the money to establish a fleet to match the Athenian one.
What is an alickadoo?
