Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
Amniocentesis is a freshly established test for identifying fetal duchenne's muscular dystrophy.
<h3>What is tested for during an amniocentesis?</h3>
Amniocentesis is a test that may be recommended to you during pregnancy to determine whether your unborn child has a chromosomal or genetic disorder like Down syndrome, Edwards syndrome, or Patau's syndrome.
<h3>What exactly does an amniocentesis entail?</h3>
A little sample of amniotic fluid is removed during an amniocentesis operation for testing. This is the fluid that a pregnant woman's fetus is enclosed in. The amniotic fluid shields the fetus from harm and is transparent and pale yellow in color. provides infection protection.
<h3>What takes place after a positive amniocentesis test?</h3>
If the test yields a positive result, the fetus may have the genetic disorder. To confirm this, more testing are sometimes required.

The Sahel. The Sahel is a region of sub-Saharan Africa and it is also a zone of ecological transition between the Sahara to the north and the wetter savannas to the south.
