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_
Explanation:
Cell Cycle Regulators. The cell cycle controls replication and apoptosis, prevents uncontrolled cell division (tumor formation), and may involve detection and repair of damage to DNA. ... Sigma offers a host of cell cycle regulators such as antimitotics, mitotic inhibitors, and cytokinesis inhibitors.
Unlike a bar magnet<span>, however, </span>Earth's magnetic field<span> changes over time because it is generated by a geodynamo (in </span>Earth's<span> case, the motion of molten iron alloys in its outer core).</span>
Answer:
Ocean temperatures can cause large storms such as hurricanes or tropical storms. Warmer ocean waters create larger and stronger storms as well as keep said storms going longer. Warmer ocean waters can also cause the temperature in the immediate air around it to be slightly warmer.
