Amblyopia, optic neuritis is a dimness of vision or the partial loss of sight without detectable disease of the eye.
Partial blindness means you have very limited vision. Complete blindness means you cannot see anything and do not see light. Decreased vision in one or both eyes without detectable anatomic damage in the eye or your vision.
Temporary vision loss (total or partial) can also be the result of migraine headaches, sickle cell anemia, also referred to as sickle cell disease (inherited blood condition) acute angle-closure glaucoma (sudden rise in eye pressure).Types of vision loss include central vision loss or difficulty seeing things in the center of vision.

Any estimate of the heritability of a particular trait is specific to one population in one environment.
The degree to which genetic variations among persons may adequately explain the variations in their attributes is known as heritability. Characteristics like height, eye color, and IQ are examples of traits, as are illnesses like schizophrenia and autism spectrum disorder.Heritability, which is denoted by the statistic h2 in science, describes the proportion of a trait's variation that can be attributable to genetic variation. An estimation of a trait's heritability is particular to one population in a particular setting, and it might alter over time as conditions change.Between 0 and 1 heritability estimates are given. A heritability near to zero indicates that environmental variables, rather than genetic differences, account for the majority of variation in a trait among individuals. Due to their lack of genetic control, traits like religion or spoken language have a heritability of zero. A heritability near to one means that genetic differences account for almost all of the variability in a characteristic, with little to no influence from environmental factors.

A dihybrid cross produces 30 recombinant offspring out of a total of 1,000 offspring. What is the recombination frequency of the two gene pairs?
The recombination frequency of the two gene pairs is 3%.
The number of recombinant offspring(r.o.) / total number of offspring x 100% = recombination frequency(θ):
r.o./total x 100% = θ
30/100 x 100% = 3%
Recombinant offspring are children that have a different allele combination to their parents.
For example, say a mother has a haploid cell with the alleles AB and the father has a haploid cell with the alleles ab. These combine to make a diploid cell with the sequence Aa+Bb.
Formation of Recombinant Offspring :
Recombination can happen in two different ways; independent assortment and crossing over.
Independent assortment is when the maternal and parental DNA are mixed during meiosis, creating a new gene sequence.Crossing over happens during the first stage of meiosis when the two homologous chromosomes are paired and a portion breaks off on the same loci then reconnects to a different end. Crossing over can only happen when there isn't a physical linkage of the parental alleles.Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis. A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way we can measure the genetic distance between two loci, based upon their recombination frequency. This is a good estimate of the real distance. Double crossovers would turn into no recombination. In this case we cannot tell if crossovers took place. If the loci we're analysing are very close (less than 7 cM) a double crossover is very unlikely. When distances become higher, the likelihood of a double crossover increases. As the likelihood of a double crossover increases we systematically underestimate the genetic distance between two loci.
When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
