What is it called when two forms of a trait are both dominant at the same time

Answers

It is called Codominance. In this condition, two forms of a trait or alleles are both present in the phenotype. For example, in feather color of hens, the alleles will be W for white and B for black. Possible genotypes in codominance will result to WW white BB black and BW speckled.

Answer: Codominance (apex)

What steps are considered when constructing a recombination map using a three-point test cross?

Answers

Constructing a recombination map using a three-point test cross is a fundamental process in genetic mapping to determine the order and relative distances between three linked genes. Here are the general steps involved in this process:

1. **Select Appropriate Organism**: Begin by selecting an organism with traits controlled by three genes that you want to map. Ensure that these genes are located on the same chromosome.

2. **Create a Heterozygous Individual**: Start with an individual that is heterozygous for all three genes of interest (AaBbCc, for example). One chromosome should carry the dominant allele, and the other should carry the recessive allele.

3. **Perform Test Cross**: Cross this heterozygous individual with a homozygous recessive individual (aabbcc). This will produce progeny with a variety of allele combinations.

4. **Observe Progeny Phenotypes**: Examine the phenotypes of the progeny resulting from the test cross. Record the number of individuals with each phenotype. These phenotypes are crucial for calculating recombination frequencies.

5. **Calculate Recombination Frequencies**: Use the phenotypic data to calculate recombination frequencies between the three genes. Recombination frequency is the proportion of offspring that show a recombination of alleles (different from the parental combination).

6. **Determine Gene Order**: Analyze the recombination frequencies to determine the order of the three genes on the chromosome. The gene with the highest recombination frequency with the others is likely to be in the middle, while those with lower recombination frequencies are on the ends.

7. **Calculate Map Distances**: Calculate map distances between the genes based on the recombination frequencies. One map unit (centimorgan) corresponds to a 1% recombination frequency.

8. **Interpolate Cross-Over Frequencies**: If the recombination frequencies are not whole numbers, interpolate to estimate the exact cross-over frequencies between genes.

9. **Create a Recombination Map**: Construct a genetic map that shows the order and relative distances between the three genes. Include map distances in centimorgans.

10. **Validate the Map**: Perform statistical tests or additional crosses to validate the accuracy of the map.

These steps help geneticists create a recombination map, which provides valuable information about the genetic linkage and the physical arrangement of genes on a chromosome.

What does a food web link together?

Answers

Doesnt it link the circle of life?
Victuals webs consist of many interconnected pabulum chains and are more authentic representation of consumption relationships in ecosystems. 
The organisms that victual the primary engenderers are called primary consumers. Primary consumers are conventionally herbivores, plant-eaters, though they may be algae eaters or bacteria eaters.
The organisms that victual the primary consumers are called secondary consumers. Secondary consumers are generally meat-eaters—carnivores.The organisms that victual the secondary consumers are called tertiary consumers. These are carnivore-victualing carnivores, like eagles or immensely colossal fish.
Some aliment chains have adscititious levels, such as quaternary consumers—carnivores that victual tertiary consumers. Organisms at the very top of a aliment chain are called apex consumers.

Why food coming from stomach is to be made alkaline?

Answers

the food coming from stomach is made to be alkaline ...
reason;
the pancreas secretions and intestinal glands only work on the alkaline solution...
 so food coming from stomach is made alkaline so that it can be easily react with the intestinal juice for digestion.....
It has to be made alkaline in order to avoid acid reflux. It is the condition where food and stomach acid push back into esophagus which may cause burning pain in the lower chest accompanied by other serious symptoms. 

Which property of carbon 14 facilitates its use in dating fossils?

Answers

Answer:

When an organism dies, its carbon-14 decays back into nitrogen-14 at a known rate, called a half-life (5,730 years). By measuring the remaining carbon-14 in fossils, scientists can estimate their age, helping us understand the history of life on Earth.
