Hexaploid wheat was produced synthetically by He and coworkers They mated the diploid species Aegilops tauschii and the tetraploid species T turgidum what is an accurate statem?

Aegilops tauschii contributed two chromosomes, and T. turgidum contributed four chromosomes.

Diploid = 2n. Tetraploid = 4n. Hexaploid = 6n.

Therefore, following meiosis you get 1n + 2n = 3n.

3n gamete ---> 6n somatic cell.

What genetic mutations are there from same family?

I don't know all of them, however, some mutations are: *Multiple Limbs (Having 2 or more thumbs, for instance) *Mental Retardation/ Downs Syndrome *Abnormal body formation (Like having one arm noticeably smaller than the other)

What is a Bachelor of Science in mechanical Engineering compared to Degree in Mechanical Engineering?

It's the same thing. If you have a degree in Mechanical Engineering, you have a Bachelor of Science in Mechanical Engineering.

Is IED a genetic diseases?

Impulsive behavior, and especially impulsive violence predisposition has been correlated to a low brain serotonin turnover rate, indicated by a low concentration of 5-hydroxyindoleacetic acid (5-HIAA) in the cerebral spinal fluid (CSF). Possible polymorphisms in the gene for tryptophan hydroxylase, which is responsible for the production of hydroxytryptophan, the precursor of serotonin. Within violent subjects, a significant relationship was observed between CSF 5-HIAA concentration and specific polymorphism genotypes. The phenotypes associated with these genotypes are extreme and it is hypothesized that these polymorphisms may only be significantly correlated to impulsive behavior

What are genetic parents?

This sounds like another way of making reference to biological or bio parents, the man and woman who provided the genetic material that formed you.

Antibiotic in gene cloning?

If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance.

There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.

Is carpal tunnel genetic or caused by being obese?

Neither. The Carpal Tunnel Syndrome is a result of repetitive movements done over a long period of time. You may be genetically prone to it or obesity may make it worse, but neither is a cause.

What virus has RNA as its genetic material?

There are many viruses with RNA. Here are a few examples: Ebola virus, HIV, and the viruses causing measles, mumps, polio, rabies, rubella, and yellow fever.

In the Baltimore classification of viruses, four of the seven major groups (classes III to VI) store their genetic information in RNA.

For further information, look at the links below.

technically hat is not true because RNA viruses don't kill.

Why does the law of independent assortment relates to crossing over and genetic linkage by?

This recombination of genes, called the crossing over of DNA, can cause alleles previously on the same chromosome to be separated and end up in different daughter cells. The farther the two alleles are apart, the greater the chance that a cross-over event may occur between them, and the greater the chance that the alleles are separated. - See more at: http://www.chacha.com/question/if-mendel's-law-of-independent-assortment-states-that-allele-pairs-separate-independently-of-each-other-during-meiosis.-how-does-this-law-relate-to-crossing-over-and-genetic-linkage#sthash.pJkZU4x9.dpuf

Has genetic engineering reduced the milkweed population?

Monsanto uses Round Up to kill weeds and has genetically made corn so that it grows with the Round Up. So areas that grow corn have no milkweed and the monarch butterfly needs milkweed to survive. Many garden clubs are encouraging people to grow milkweed in their gardens and get highway departments to stop mowing roadsides where milkweed grow.

Why do Groups of people living next to one another tend to share more genetic traits than groups living far apart?

The same reason why people change when they get new friends, to blend in. The same goes for races, as Americans blend together more so than Americans and English or Americans and the Casino Indians.

Is there any cure for of a genetic disease called Angelman's syndrome?

Angelman's syndrome is a genetic disorder caused by deletion on genes on chromosome 15 contributed by the mother to child, once you are born with it, the faulty gene has already done the damage. There is no cure for it.

Note: If their deletion of the same gene on chromosome 15 contributed by the father, it results in Prader Willi syndrome.

What is the Structure of histones and non histones?

Histones are the major protein structure of chromosomes. The DNA is wrapped twice around a histone octamer to create a nucleosome, which are assembled six at a time to make a Solenoid. Solenoids coil into a scaffold, which is then coiled itself to make the chromosomal matrix.

Where is the genetic material in sperm located on a cow?

The genetic material in sperm is located in the Cattle thymus gland on a cow.

What is the word for the genetic disorder that causes abnormal hemoglobin is known as?

sickle cell anemia. If you are only heterozygous for this disease it is simply called sickle trait.

Why light band come in agarose gel for amplified PCR product?

you mean faint band? you must have to optimize it. There might be several reasons, you have to play around with the PCR program, concentration of dNTPs, co factors such as Mg or Mn, etc.

Are genetic equilibrium and evolution the same?

No. Evolution is the change in allele ( different molecular forms of the same gene ) frequency over time in a population of organisms. No equilibrium there.

What makes a mule pony and is a mammoth jack the same as a donkey?

A Mammoth Jack is a LARGE donkey. The link below shows 'King Kalico' who stands 64 inches tall at the withers.

A mule pony is a miniature mule, 48 inches or less at the withers. You can buy one (or more) at the link listed below.

What causes sporadic ALS?

Sporadic ALS has no known cause. While many environmental toxins have been suggested as causes, to date no research has confirmed any of the candidates investigated, including aluminum and mercury and lead from dental fillings.
