What is the incidence of infertility with identical twins?
Most people will answer this by explaining that the twins will run the same risk are normal adults. However, if the twins are monozygotic they may also be "mirror-twins", in which one twin would have an increased chance of displaying situs inversus, a condition where the organs are flipped (mirrored to other twin). This in and of itself isn't harmful, but the origins of situs inversus are believed to be in the earliest stages of development, arising from cilia that move clockwise instead of counter-clockwise, thus moving the cells that will form organs to the wrong side. Going back to questions of infertility, it is known that this wrong-turning cilia cannot play a normal roll in some biologic functions, including driving the bending movement required for sperm (cilia structures of the tail) to be motile. In this way, male infertility (sterility) could theoretically be affecting at a higher incidence in man mirror twins with situs inversus.
When is angle of incidence equal to angle of reflection?
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
What are rachipagus conjoined twins?
The twins that are connected from the Dorsal or rear union at the spine. Very rare incidence.
How common are fraternal twins?
In the US, the incidence of fraternal (dyzygotic) twins is 32 in 1000 live births.
What cultural race has the highest incidence of twins?
The Yoruba people of Nigeria have the highest incidence of twins in the world, with about 45-50 twin births per 1,000 deliveries. This high rate of twinning is attributed to genetic factors and diet in the Yoruba population.
Do fraternal twins only run on mother's side?
Yes. Fraternal twins are due to two eggs being released. No - If they are on either side of the family, the incidence of twin pregnancy is increased, whether they run on the mum's side or the dad's side. And in addition to the above answer, fraternal (non-identical) twins are due to two different eggs being fertilised by two different sperm.
What are conjoined twins and do they occur?
Conjoined twins are a rare phenomenon where two embryos fail to fully separate during early development, resulting in twins that are physically connected at certain parts of their bodies. This condition occurs in approximately 1 in 200,000 live births, although the exact incidence can vary. The degree of connection and shared organs can differ significantly among conjoined twins, leading to unique medical challenges and considerations. While conjoined twins are extremely rare, they do occur and often require specialized medical care.
What is the formula for angle of incidence?
The formula for calculating the angle of incidence is: Angle of Incidence = Angle of Reflection. The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence.
The angle of reflection is equal to the .......?
The angle of incidence
What is the angle of incidence to the normal incidence?
The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface. In normal incidence, the incident ray is perpendicular to the surface, so the angle of incidence is 0 degrees.
What is the incidence of tax?
Tax incidence refers to who actually pays the tax. Tax incidence can be divided into 1. formal incidence :the party liable to the tax 2. Informal incidence :party who actually pays the tax, The tax incidence is decided by the elasticity of demand and supply for a good or service.
What is a sentence for angle of incidence?
I can't find a sentence for the angle of incidence.
What is plural for incidence?
The plural form of incidence is incidences.
Are there fewer conjoined twins today than in the past?
The incidence of conjoined twins has remained relatively stable over time, occurring in about 1 in every 200,000 live births. Advances in medical technology and prenatal care may lead to improved outcomes for conjoined twins, but they do not significantly reduce the occurrence rate. Factors such as maternal age and genetic predispositions can influence the likelihood of conjoining, but overall, the prevalence has not shown a marked decrease.
