Mars2501 [29]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options but the complete question is in the attached picture below.

The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.

It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.

What do the letters inside the grid of a punnett square represent?

Aneli [31]

Answer:

The correct answer is - Genotype of the offspring

Explanation:

Punnet square is a diagram which is used to predict and show the genotype of offspring that is produced by a cross between male and female gametes. This approach was given by Reginald C. Punnett.

Each grid have a genotype that can determine the phenotype of offspring. The letters used in to fill these grids can be made up of uppercase letters, lower case letters or both. The allele shown in upper case letters shows that the allele is dominant and the allele which is in lowercase letter is a recessive allele.

Therefore the letters inside the grid of a punnet square represents the genotype of the offsprings.

True or False: If one thing in a food web is affected, it will only probably affect the organism that directly relies on it for

joja [24]

Answer:

False

Explanation:

Due to the fact that all the organisms are connected in a chain, the energy flow would be affected and that would result in many organisms being deprived of energy they need and that creates a chain effect.
