It's the only bacterium that contains this enzyme. It can withstand the elevated temperatures that are required to unwind DNA. These bacteria contain more DNA polymerase than any other species. Why are there so many possible combinations of maternal and paternal traits in each generation of offspring?

Because there are the same number of chromosomes in each cell B. Because of the random grabbing of chromosomes by the microtubules during metaphase I C. Because of the biological components that chromosomes are made of D. Because of the high frequency of viral invasion Which of the following most contributes to a large variation of traits inherited by an offspring?

Genetics test questions

Production of polar bodies B. A small gene pool C. Random shuffling of homologous chromosomes in gamete production Why are there more males with color blindness than females?

The gene for color blindness is found on the Y chromosome. The recessive gene is usually masked by another X chromosome in females.

If a piece of DNA breaks off a chromosome and attaches itself to a nonhomologous chromosome at another location, what type of change has occurred? During the transcription of a certain protein, an extra cytosine was placed into a gene region, throwing off the correct amino acid sequence.

What type of mutation occurred? DNA requires which of the following? To reduce the chromosome number to haploid in the resulting daughter cells 4. The genetic disorder sickle-cell anemia is an example of A. What is the key difference between mitosis in plant cells and mitosis in animal cells?

A cell plate is formed during mitosis in plant cells 6. Which of the following genotypes causes Klinefelter syndrome?Just choose which subject you want to study: genetic concepts, Mendel's laws, non-Mendelian inheritance, linkage and crossing over, sex chromosomes and sex-linked inheritance, blood types, karyotypes and genetic diseases, the Hardy-Weinberg equilibrium and genetic engineering.

Study Questions. Mendelian Genetics Overheads. Genetic Topics: Mendel's First Law of Genetics (Law of Segregation) Genetic analysis predates Gregor Mendel, but Mendel's laws form the theoretical basis of our understanding of the genetics of inheritance.

To test this hypothesis, Mendel selfed the F 2 plants. If his law was correct he.
