It was commercially introduced in 1839, a date generally accepted as the birth year of practical photography. The metal-based daguerreotype process soon had some competition from the paper-based calotype negative and salt print processes invented by William Henry Fox Talbot
The most reasonable prediction to account for the deviation from the expected results is: in sweet pea plants, the gene for flower color and the gene for pollen grain shapes are genetically linked.
<h2>
Who is the Father of Genetics?</h2>
Gregor Mendel is known as the Father of Genetics, as he established the principles governing the:
- Laws of independent assortment,
- Dominance, and
- Segregation of genes.
However, certain exceptions to these principles exist, such as genetic linkage, which is an example of an exception to the law of independent assortment.
<h3>
What is Genetic Linkage? </h3>
Genetic Linkage is the likelihood for genes or fragments of DNA adjacent together via chromosome to segregate simultaneously at meiosis and hence be inherited together.
The outcome of the parameters given can be interpreted as follows:
- According to the Law of Independent Assortment, we need to know that two or more alleles of distinct genes assort separately or independently.
- The genetic linkage takes place in the provided scenario, but it does not match the 9:3:3:1 ratio. This is because the genetic linkage does not obey the principles of independent assortment, hence, fewer purple offspring are produced.
- As a result, mutations can cause Mendel laws to fail and have an effect on an organism's phenotypic features.

Someone has asked this question before and I answered it I don’t want to type it all over again so here
While performing a physical examination on Denny French, Dr. Giles used an ophthalmoscope to examine Denny's eyes.
<h3>What is a disease?</h3>
A disease refers to any harmful and abnormal deviation of the body or body parts such as the eyes of a living organism from its normal structure or functional state due to the actions of pathogens, and it's typically accompanied by certain signs and symptoms.
<h3>What is an
ophthalmoscope?</h3>
An ophthalmoscope can be defined as a type of instrument that is designed and developed to be used by an ophthalmologist to physically examine the interior of a patient's eye.
In this context, we can infer and logically deduce that while performing a physical examination on Denny French, Dr. Giles used an ophthalmoscope to examine Denny's eyes.
