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

Biology

Zepler [3.9K]3 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.

What happens to sister chromatids in meiosis II? *
3241004551 [841]

Answer:

Sister chromatids found in each of the cells previously originating in meiosis I are separated during meiosis II.

Explanation:

Meiosis is the process of cell division used to obtain sex cells or gametes. Unlike mitosis, the daughter cells obtained in meiosis have half the chromosome charge, i.e. they are haploid.

The result of meiosis I is two haploid daughter cells, in which each chromosome is made up of two sister chromatids, still attached. During meiosis II, whose duration is short, the sister chromatids separate, and each cell will give rise to two haploid daughter cells.

The end result of meiosis I and II is four haploid daughter cells, which become gametes.

Which property of water remains unchanged when it recycles in the atmosphere
zzz [600]

Answer:

Molecular arrangement is the property of water remains unchanged when it recycles in the atmosphere .

Explanation:

In the water, Molecular arrangement remains same when it recycles in the atmosphere . A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent.

This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.  Thus it is the element or property which remains in same condition.

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide ch
HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.

<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

Based on this conversation, write an email to your friend (between 200-400 words), explaining to him why his studying habits are
34kurt

Dear Sarah.

Firstly, I am very happy to know that you have decided to start a study schedule for your literature course in Colonial Latin America, I believe that you will gain great knowledge and that this will be very important for your academic career.

Because of the importance of this study, I decided to analyze your study methods and I fear that they are not efficient and that you will lose time and do not absorb the concepts really necessary for you.

Your study method is based on memorizing concepts and quotes and I believe that you should not rely on it to study, as our memory is relative and often does not last as long as necessary. So I decided to give you advice that I used during my study and that were extremely efficient.

My first advice is that you divide all the material that you have to study in small modules and establish an expert for the study of each one. Don't forget to put a rest time so that you don't get overwhelmed and start taking your readings automatically.

My second advice is that when you study each module, write summaries with the main parts and make mind maps that will be extremely necessary to make revisions.

My last and most important advice is that you make constant reviews and try to conceptualize and reason during this process, this will prevent you from memorizing, but introducing the concepts in your mind in order to understand them and not record them.

I am grateful that you will be successful if you follow these steps and I expect answers from you telling me the results.

Affectionately,

Caroline.
