In general, the frequency of crossing over between two linked genes depends on what?

How far apart they are on the chromosome
The characteristics that the genes code for
Whether the genes are dominant or recessive
The phase of meiosis in which the crossing over occurs

Answers

Answer 1

Answer:

Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.

The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.

Answer 2

[tex]\huge{\color{magenta}{\fcolorbox{magenta}{black}{\huge{\color{white}{\fcolorbox{aqua}{black}{✿ᴀɴsᴡᴇʀ✿}}}}}}[/tex]

If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.

The processes of transcription and translation are critical pieces of gene expression to produce proteins in all living cells on earth.
Which statements correctly differentiate transcription and translation? More than one statement may apply.

Answers

Transcription is the process of synthesizing RNA from DNA, while translation is the process of synthesizing proteins from RNA.

Transcription involves the production of a complementary RNA copy of a DNA sequence, using RNA polymerase and nucleotides. The resulting RNA molecule, called messenger RNA (mRNA), carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.

Translation, on the other hand, involves the reading of the mRNA sequence by ribosomes, which assemble amino acids into a polypeptide chain according to the genetic code. This process involves transfer RNAs (tRNAs) that carry specific amino acids and match them to the codons on the mRNA. Together, transcription and translation enable the transfer of genetic information from DNA to proteins, which perform vital functions in cells.

Answers

Great question! In my opinion anyone can do anything as long as they have the qualifications, take John for example. Let’s say he is a random guy from New York with no genetics in the police department. If john takes the tests and training and qualifies as a police man, it shouldn’t matter what his genetics are. I think testing however is a good idea due to the fact it narrows down the participants who in theory should be good at it etc. And separates the strong from the weak. Hope this helps!

The statement 'very few new human diseases have originated in other animals because the genetic differences are too great' regarding viral diseases is false.

What is a viral disease?

A viral disease is an infection caused by a virus that may be spread to cause pandemic and epidemic situations.

Viruses are non-living forms and/or entities that are present in a suitable host to reproduce and survive.

In many situations, viruses mutate in order to pass from a type of host (animal) to a human host.

The carrier genotypes are Aa while any non carriers are AA, and any affected would be aa.

You would go through each of the pairs and do a pedegree to find out the genotypes of the offspring they produce.  For 1 it would be a pedegree for Aa from the mom and AA from the dad.  There offspring would be 1/2 Aa and 1/2 AA.

For number 2 it would be Aa for the mom and Aa for the dad. There offspring would be 1/4 AA, 1/2 Aa, and 1/4 aa.

For number 3 the mom would have AA and the dad would be aa.  There offspring would be 4/4 Aa

For number 4 the mom would be Aa and the dad would be AA.  There offspring would be 1/2 AA and 1/2 Aa.

Cell cycle is the series of events in which cell grows and duplicate to form daughter cells.

It has two phases:

Interphase: in this phase cell synthesize, grow, produce mRNA and protein and replicate cell's DNA. It is divided into: G1, S and G2 phase.M-phase: in this phase actual cell division takes place.

Improving water efficiency reduces operating costs (e.g., pumping and treatment) and reduces the need to develop new supplies and expand our water infrastructure. It also reduces withdrawals from limited freshwater supplies, leaving more water for future use and improving the ambient water quality and aquatic habitat. More and more utilities are using water efficiency and consumer conservation programs to increase the sustainability of their supplies. Case studies demonstrate substantial opportunities to improve efficiency through supply-side practices, such as accurate meter reading and leak detection and repair programs, as well as through demand-side strategies, such as conservation-based water rates and public education programs.Supply-Side Strategies for Water Suppliers Accounting for WaterAccounting for water is an essential step toward ensuring that a water utility is sustainable. This is best accomplished when water systems meter use by their customers. Metering helps to identify losses due to leakage and also provides the foundation on which to build an equitable rate structure to ensure adequate revenue to operate the system. Water Loss ControlNational studies indicate that, on average, 14 percent of the water treated by water systems is lost to leaks. Some water systems have reported water losses exceeding 60 percent. Accounting for water and minimizing water loss are critical functions for any water utility that wants to be sustainable. Demand-Side Strategies for Water Suppliers Water RatesOne of the most effective ways to reduce demand for water is to establish rates that escalate as more water is used. Consumer EfficiencyConsumers can reduce water use by installing water-efficient products or employing efficiency practices, such as turning the water off while brushing teeth or running washing machines only when they are full. Water systems can promote these actions through consumer rebate and education programs. EPA's WaterSense ProgramWaterSense seeks to protect the future of our nation's water supply by promoting water efficiency and enhancing the market for water-efficient products, programs, and practices. Visit the website for information on water-efficient products and practices, as well as utilities who offer rebates for WaterSense labeled products.
