Mary marries an unaffected man, justin, whose paternal uncle has galactosemia. determine the genotypes for justin's family.
vitfil [10]
1. Galactosemia is a disease that will only be expressed when a person is<span><span><span> homozygotic recessive for that trait. It's the same as saying it </span> has</span> 2 recessive alleles.

Dominant allele-</span><span> G
recessive allele- g
</span>
Homozygotic dominant:  GG <span><span>(doesn't express the disease)
</span>Heterozygotic : Gg (doesn't express the disease)
Homozygotic recessive: gg (expresses it)</span>

2.
-Mary has this genotype: G_ . This means it can be GG or Gg
-The exercise already says that justin's mother is GG (<span>Homozygotic dominant)
</span>- If his mother is GG, one of these G's is going to be passed to Justin. So, his genotype is either GG or Gg. Since we are not sure we write as: G_.
Justin's genotype: G_

3.
-
Justin's uncle has galactosemia so his genotype is: gg

-
If the uncle was able to receive two recessive alleles it means the mother had one to pass, and so did the father. However, in the diagram, it's not pointed out that they have a disease so it only leaves one possible genotype: Gg. Justin's grandparents are both Gg.

4. The last person to analyze is Justin's father.
If we crossed the grandparents (Gg x Gg) we could obtain these genotypes: GG, Gg, gg.
Justin's father doesn't express the trait, so it's not gg. That leaves us with either GG or Gg. Since we can't know for sure, onece again we write as G_
Justin's father: G_

Students construct a graphic organizer to illustrate the different levels of biological organization.
erastovalidia [21]

Answer:

B--Organism

Explanation:

Different levels of biological organization start from the least complex object and end at the most complex. Every object has objects preceding it that it is made up of.

In this question, the organ system is made up of several organs. A community is made up of several populations of different people. Think about this now: what makes up a population and is made up of organ systems? The most logical answer here according to the flow is B--an organism. An organism is made up of organ systems and makes up a population, which in turn allows several populations to make up a community.
