Does hemophilia skip a generation?

Haemophilia is a sex-linked recessive disorder - which means it can skip a generation, but only if it is carried in the female line.A female can be a carrier of haemophilia, but a male cannot. This is because males only have one X chromosome, so if they have a defective X they will have the disorder. If a father has haemophilia, all of his daughters will also have haemophilia.


What model is used to show the pattern of pattern of traits that are passed from one generation to the next in a family?

The model used to show the pattern of traits passed from one generation to the next in a family is a pedigree chart. This chart displays the inheritance of traits and helps to track genetic patterns within a family over multiple generations.


How many individuals would be expected to show that a trait in a F2 generation consisting of 80 individuals?

In a F2 generation of 80 individuals, you would expect about 3 individuals to show a trait that follows a typical Mendelian inheritance pattern with a 3:1 ratio in the offspring generation. This is based on the expected ratio of 1:2:1 for a heterozygous cross.


What did mendel conclude after his stem height pea plant experiment?

Mendel's experiment showed that with other traits it showed a similar pattern and also that it resulted that this crossed the first generation. The dwarf height traits had seemed to disappear. He then let the first generation plants self pollinate.


F1 refers to what in biology?

F1 refers to the first generation of offspring (children) of two individuals. It can refer to many different organisms, not just animals. P would be used to indicate the 2 parents, and F1 are their children (and F2 would be the second generation of offspring of P, so P's grandchildren and F1's children, and so on) These P and F terms are terms from the field of genetics, used in the study of natural populations and crossing experiments. A famous example is the crossing experiments with peas by Gregos Mendel, who was the fouder of these types of studies.

Will there be a pokemon Generation VI?

As of yet (July 31, 2011) there has been no confirmation or announcement of Game Freak developing a sixth generation of Pokemon. However, because of the franchise's global success and popularity, another generation seems likely. If following the pattern of the previous two generations, (hypothetically) Generation VI should start sometime in late 2014 - 2015.


What is the bolt pattern of 97 Prelude Si 4-stud rim?

I believe regardless of what market and trim level it was in, the 5th generation Honda Prelude ('97-'01) had a 5x114.3 bolt pattern. The 4th generation ('92-'96) had a 4x114.3 bolt pattern.


What Pokemon was somewhat described in Red Blue and Yellow Version on Route 10 that now exists in the 5 generation?

What pattern is apparent in pedigrees charting the inheritance of a recessive trait?

The person with the recessive trait seems to 'skip' a generation


What is pattern generator?

A specific pattern can identify a fault. For example, if the first input of an AND gate is struck at zero, then a test vector of 10 or 11 can identify that fault. These two vectors are called as a test set. Generation of such a pattern is done by a pattern generator.


What type of rock is unlikely to have a fossil in it?

Igneous rock does not normally preserve fossils. But hot rock or ash will occasionally preserve the shape as a molded impression.The rock you most likely will find a rock in is a sedimentary rock because the pattern of the organisms in the sediment is preserved.


What is the lug pattern on a gen 1 Mazda RX7?

All 1st generation RX7's have a 110 x4 bolt pattern, except the GSL-SEs are 114.3 x 4.


What theory has been used to explain the pattern of rapid evolution that often occurs after a mass extinction event?

The theory of rapid evolution rather than over a very long time.


To describe how traits can disappear and reappear in a certain pattern from generation to generation Mendel proposed?

Mendel proposed the concept of dominant and recessive alleles that determine trait expression in offspring. Through his experiments, he discovered that traits can disappear in one generation due to being masked by dominant alleles, but can reappear in future generations when those recessive alleles are passed down and expressed. This pattern of inheritance is now known as Mendelian genetics.
