d1i1m1o1n [39]

The genotyoe of the offspring can be obtained from the genotype of  the parents using a punnet square.

<h3>What is genotype?</h3>

The term genotype refers to the sum total of the genes that an organism receieves from its parents. We have to note that genes often occur in pairs called alleles. The combination of gene alleles controls the expressed trait in the organism.

This question is incomplete. However, we do know that the genotyoe of the offspring can be obtained from the genotype of  the parents using a punnet square.

What causes the formation of graded beds of sediment?​
Mamont248 [21]

In geology, a graded bed is one characterized by a systematic change in grain or clast size from one side of the bed to the other. Most commonly this takes the form of normal grading, with coarser sediments at the base, which grade upward into progressively finer onesI just learned about this in our rocks and minerals unit for science,

How could the situation in Haiti be improved?
In-s [12.5K]

Answer:

Billions of dollars of foreign aid has poured into Haiti with little to show for it. This is largely because that money has come to do for Haitians what, with a little help in expertise, they could have done for themselves. This is the biggest difference between aid and development. As a result, 74% of Haitians are either unemployed or under-employed and 8.5 million live on less than $2.41 per day.

Aid is designed to help with immediate needs. As important as that is at times, aid is not the solution to Haiti’s long term challenges. The Haitian people are the solution to Haiti’s problems, particularly those who have the skills and character to build a stronger Haiti for all.

By helping men and women gain the skills to build, train, and lead, you have the power to unleash Haiti’s potential to create a stronger future. Through Extollo’s unique approach to development you will help build stronger careers, stronger families, stronger communities, and a stronger infrastructure for all Haitians.

For plants and other organisms to develop differences among their respective species the alleles of their genes must contain var
olasank [31]

A) <u>Mutation</u> is the original source of variations for plants and other organisms  which develops differences among their respective species

Explanation:

Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.  

A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.  

Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
