Why would two sets of identical twins that marry not have children that look alike?
Even identical twins are heterozygous for many alleles. Recombination would produce gametes with many different combinations of those alleles in each individual. Their offspring, as a result, could have very different genotypes than either parent, and thus look different as well.
How do the laws of segregation and independent assortment affect the analysis of inheritance patterns?
The law of segregation states that alleles segregate independently during gamete formation, while the law of independent assortment states that alleles of different genes assort independently of one another. These laws help predict inheritance patterns by explaining how different alleles are passed from parents to offspring, and how they can recombine independently during genetic recombination. By understanding these laws, geneticists can better analyze and predict the inheritance of traits in offspring.
If identical twins marry identical twins could at least some of their kids look like twins having similar fingerprints?
They may look alike, but they will never have the same fingerprints, because fingerprints are created by differences of thickness in the dermal layer. It is independent of genetics, therefore, twins will never have identical fingerprints and any similarities between twins fingerprints would merely be coincidental.
What are the chances of having kids that can roll their tongue if a heterozygous tongue roller has kids with someone who cannot roll?
If one parent is heterozygous for the tongue rolling gene (Tt) and the other parent cannot roll their tongue (tt), the chances of their children being tongue rollers (Tt) is 50%. The other 50% chance is that the children will not be able to roll their tongue (tt).
How does meiosis serve as the basic of genetic variation?
In meiosis, genes crossover, there is independent assortment (each pair of alleles segregates independently of each other pair of alleles during gamete formation), and the law of segregation (the two alleles for a heritable character segregate during gamete formation and end up in different gametes (daughter cells)). In meiosis, what genes an offspring inherits from each parent is decided. In humans, there are at least 8 million different variations of children.

What are eleven identical children called?
Eleven identical children are called undecaplets.
What is the probability that the children will be heterozygous?
Being born with six fingers is actually a dominant trait and the probability of the children would be 75% with six fingers and 25% with five fingers if both parents were heterozygous for that trait. If both parents were homozygous dominant for that trait then there is a 100% probability of the children being born with six fingers.

What are five identical children called?
Five identical children born at the same time are referred to as pentuplets.
What is the probability of getting exactly 2 boys out of 3 children?
There is no simple answer to this question because the genders of children depend on the parents genes and age and so are not independent events. Also, the probabilities of the two genders are not equal. Further, some of the children may be identical twins or triplets. Assuming, however, that the genders are independent, the answer is 0.3872, approx.
If children with blood group O and a what could be the blood group of parents?
both parents could be A heterozygous or one A heterozygous and the other O
Will parents with a positive blood type have children with a positive blood type?
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
What blood groups do children have if parent have B and A blood group?
Depends on if they are homozygous (two identical genes) or heterozygous (two different genes). A+O mates with B+O and the offspring can be AB, AO, BO, or OO in equal proportions. However, if one is AA and the other BB, then 100% are AB. Finally, there is AO + BB and AA + BO. By now you can figure out the proportions.
What is a probability of 2 Rh plus heterozygous have 4 Rh- children?
1/8 or 12.5%
What are the genetic priciples of identical twin case?
In the case of identical twins, a single embryo divides into two completely separate and genetically identical embryos. Each embryo continues to grow and develop individually, but with the exact same genes as the other.On an interesting side note: Children of identical twins are genetically as closely related to their parent's identical twin as they are to their identical twin parent. Genetically, both twins are the parent of the other's children. Also, their children are genetically half-siblings.
Can children that are not twins have the same DNA?
In practice no, since the amount of variation is incredible due to the haploid nature of the sperm and egg, and due to independent assortment and 'crossing-over' durin meiosis. However, as is with all odds based questions, yes it is theoretically, and technically possiblem, but in reality, no.
