Answer:

The condition is known as Vesicoureteral reflux (VUR)

Explanation:

Vesicoureteral reflux (VUR) is a pathological condition caused by Urinary Tract Infections (UTIs) where urine flows back from the bladder into one or both ureters, and sometimes back into the kidneys. The condition is commonly seen in young children under 2 years of age, and infants.

Most children with primary VUR were born with an abnormal ureter, which is mainly seen as a defective valve between the kidneys and the ureters that does not close well, hence resulting in refluxes. Secondary VUR develops due to some pathological conditions affecting the urinary tract, like blockage of the urethra, causing reflux of urine. Defective bladder nerves can also lead to VUR.

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_

A coin is flipped three times resulting in three heads. What is the probability that a fourth flip will be heads? 75% 25% 100% 5
Vinvika [58]
I think it would be 50% because it could land on heads just as much as it lands on tails. its a even chance it could land on whichever it chooses to.
