Biology

Genetic Disorder: Argininosuccinic Aciduria (use for bottom section)

Mode of Inheritance: By an autosomal recessive trait

Scenario 1

Both parents are afflicted with the genetic disorder.

Parent Genotypes: aa X aa

Parent Phenotypes: Argininosuccinic Aciduria X Argininosuccinic Aciduria

Punnett Square showing the possible offspring:

a a
a aa (afflicted) aa (afflicted)
a aa (afflicted) aa (afflicted)

Possible Offspring Genotypes: All offspring are aa

Possible Offspring Phenotypes: afflicted with Argininosuccinic Aciduria

Probability Offspring will be afflicted with the disorder: 4/ 4 = 1 = 100%

Explanation of the results: Both the parents are afflicted with Argininosuccinic Aciduriait means they have both the recessive alleles.

therefore all children have both alleles recessive

Hence all childrens are afflicted.

=======================================================================================

Scenario 2

One parent is afflicted with the genetic disorder, and the second parent does not have the disorder and is not considered a carrier.

Parent Genotypes: aa X AA

Parent Phenotypes: Argininosuccinic Aciduria X Normal

Punnett Square showing the possible offspring:

a a
A Aa (Carrier) Aa (Carrier)
A Aa (Carrier) Aa (Carrier)

Possible Offspring Genotypes: All offspring are Aa

Possible Offspring Phenotypes: All are carrier

Probability Offspring will be afflicted with the disorder: 4/ 4 = 1 = 100%

Explanation of the results: one of the parents are afflicted with Argininosuccinic Aciduriait while other is normal therefore their childrens have one allele is  the recessive alleles.

therefore all children are carrier.

======================================================================================

Scenario 3

One parent is afflicted with the genetic disorder, and the second parent is considered a carrier.

Parent Genotypes: aa X Aa

Parent Phenotypes: Argininosuccinic Aciduria X carrier

Punnett Square showing the possible offspring:

a a
A Aa (Carrier ) Aa (Carrier )
a aa (afflicted) aa (afflicted)

Possible Offspring Genotypes: Aa (50% ) & aa (50%)

Possible Offspring Phenotypes: Carrier (50% ) & afflicted (50%)

Probability Offspring will be afflicted with the disorder: 2/ 4 = 1 /2 X 100 = 50%%

Explanation of the results: one of  the parent is  afflicted with Argininosuccinic Aciduriait & other is carrier.therefore 50% of their children are afflicted & 50% are carrier.

=======================================================================================

Scenario 4

Neither parent is afflicted with the genetic disorder, nor are they considered carrier.

Parent Genotypes: AA X AA

Parent Phenotypes: Normal X Normal

Punnett Square showing the possible offspring:

A A
A AA ( Normal) AA ( Normal)
A AA ( Normal) AA ( Normal)

Possible Offspring Genotypes: All offspring are AA

Possible Offspring Phenotypes: all are normal

Probability Offspring will be afflicted with the disorder: 0/ 4 = 0%

Explanation of the results: Both the parents are normal therefore they does not have any recessive allele.

therefore all children are normal.

Genetic Inheritance Patterns: Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked
Genetic Inheritance Patterns: Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked. Apparently the dominant forms are often less severe. Usher’s Syndrome is an autosomal recessive inheritance (i.e., you must get a copy of the defective gene from your Mom and one from your Dad). Autosomal means it is not carried on one of the chromosomes that determines sex.

In humans, hypercholesterolemia is a dominant autosomal disorder. Color-blindness is a recessive disorder carried on the X-chromosome. A woman with normal vision who does not have hypercholesterolemia takes her daughter to a doctor for an examination. In the course of the examination, the doctor discovers that the girl is color-blind and has hypercholesterolemia. What does the doctor automatically know about the genotype and phenotype of the girl’s father?
