What information can be inferred if the estimated heritability of a trait is approximately 0.50?

Zepler [3.9K]4 years ago

Answer:

Variability in a trait is due to a combination of environmental and genetic factors, where at least 50% can be attributed to genetic differences.

Explanation:

The heritability of a trait is the influence of both, environment and genes, on the <em>phenotype variation</em> among individuals. The <em>proportion</em> between phenotypic variation and variation in genetic values is defined as heritability.

There are 2 types of heritability: <em>Broad sense</em> (genetic variation due to dominance and epistasis) and <em>Narrow sense</em> (genetic variation due to additive genetic values).

<em>Heritability estimation</em> is based on observations and empirical data analysis, which used mathematical models like Breeder's equation and statistical analysis. An 0,50 value indicates that variability in a trait is due to a combination of environmental and genetic factors, and <em>genetic differences among individuals account for 50% of the variability in the trait</em>, so it can be inferred that the trait is very complex, like a multifactorial condition, for which the environment can play an important role.

Why is it that although single myosin molecules have a polarity, the myosin in thick filaments is
aliya0001 [1]
Polarity of a molecule does not involve the symmetry of the molecule rather it deals on with the presence of net charges and partial charges. It would be due to the partial charges present in the <span>single myosin molecules that causes its polarity. Hope this helps. Have a nice day.</span>

What is unusual about Earth’s mantle being exposed?
cluponka [151]

Answer:

There is no actual way that the mantle could be...'exposed' or 'seen'. But scientists have managed to find multiple ways to analyze the mantle and it's actual existence by using multiple devices. The mantle is basically a 2,900 kilometers (1,802 miles) thick blocks of rocks and minerals underneath the crust(or the surface of the earth) , and makes up a whopping 84% of Earth's total volume.

algol13

Answer:

The correct option is: 4. Heat at 62.8 degrees C for 30 minutes

Explanation:

Pasteurization is the process or technique of heating packaged as well as the unpackaged liquid food, to remove pathogens and extend the shelf life. In this process,<u> the food is usually heated at temperatures below 100 °C.</u>

Originally, this process involved heating the food at 72.2 °C for 15 seconds and <u>62.8 °C (145 °F) for 30 minutes, for batch pasteurization.</u>
