how does the gene regulate the quality attributed to the height of the plant
Answers
Answer:
Plant genetics is the study of genes, genetic variation, and heredity specifically in Plants.[1][2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Plant genetics is similar in many ways to animal genetics but differs in a few key areas.
The discoverer of genetics was Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (most famously pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Much of Mendel's work with plants still forms the basis for modern plant genetics.
Plants, like all known organisms, use DNA to pass on their traits. Animal genetics often focuses on parentage and lineage, but this can sometimes be difficult in plant genetics due to the fact that plants can, unlike most animals, be self-fertile. Speciation can be easier in many plants due to unique genetic abilities, such as being well adapted to polyploidy. Plants are unique in that they are able to produce energy-dense carbohydrates via photosynthesis, a process which is achieved by use of chloroplasts. Chloroplasts, like the superficially similar mitochondria, possess their own DNA. Chloroplasts thus provide an additional reservoir for genes and genetic diversity, and an extra layer of genetic complexity not found in animals.
The study of plant genetics has major economic impacts: many staple crops are genetically modified to increase yields, confer pest and disease resistance, provide resistance to herbicides, or to increase their nutritional value.
The height of the plant is determined by the presence of genes coding for tallness and shortness in plants.
Explanation:
The genes present on the chromosomes of the parent gets paired and the traits get transferred to plants or nay organism.
The Mendel's law of Dominance states that the dominant trait masks the recessive trait.
In the concept of height tall is dominant to short so when tall homozygous parent and short homozygous parent plant are crossed all the siblings will be heterozygous tall.
While in selfing of heterozygous parent plant 50% chances of short plant is there.
There are certain growth hormones which are responsible for height of the plant. Suppose the plant is tall it means that the enzyme coding high concentration of hormone is controlled by the protein. This protein is being translated by gene which makes more protein hence the plant will be taller.
