Document Summary

_a type of inheritance that does not follow strict patterns of dominant vs. recessive. _there are several different types we will explore. _also may involve more than two alleles, in an individual or population. _incomplete dominance: one allele not completely dominant in heterozygote ; both alleles provide input. _abo blood groups in humans controlled by three alleles in the population, even though single individual gets two. _a and b are dominant over o and co-dominant with each other; results in 6 genotypes and four phenotypes (a, b, ab, and o) _in past used to disprove or suggest parentage in paternity suits, now dna technology used. _o is the absence of the a or b markers on blood cells. _rh is associated with whether you are positive or negative. Mendelian, yet is considered here because of association with red blood cells. If both abo and rh status is provided this becomes a dihybrid cross.

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see

(CHOOSE ONE: all short fur; some short and some long fur; all long fur) offspring.

Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see

(CHOOSE ONE: all short fur; some short and some long fur; all long fur) offspring.

Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see

(CHOOSE ONE: all short fur; some short and some long fur; all long fur) offspring.

Procedure:

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Science assignment

Now that you are more familiar with the benefits, risks, and impacts of biotechnology, it is time for you to take a*stand! Your task is to choose one of the following types of biotechnology: genetic engineering, cloning, or artificial selection.

You will then write a one- to two-paragraph summary describing your chosen type of biotechnology. You will then need to argue for either the benefits or the risks of your chosen type. Your arguments should present your position, and then give the evidence that led you to this position. Be sure to include the following in your argument:

a description of your chosen type of biotechnology (genetic engineering, cloning, or artificial section)
one benefit or one risk for the individual (based on whether you are for or against it)
one benefit or one risk for society (based on whether you are for or against it)
one benefit or one risk for the environment (based on whether you are for or against it)
A picture (you may hand draw, take photos in nature, or use stock images)

You may get creative on this activity. You may choose to create a brochure, write a letter, or create a presentation using software. If you are unsure if your idea or software for a presentation will work, contact your instructor for assistance.

You can use the planning template below, if you wish. Be sure to write your PARAGRAPH/S in your own words and in complete sentences.

Type of biotechnology that I chose:

Description:

Are you for or against it?

One benefit or risk to the individual:
