I think how many genes code for a Mendelian is 2
The Hubble Telescope is used for the observation of stars and galaxies that are far away from the universe and also for viewing the planets in our solar system.
<u>Explanation:</u>
It was 1990 when, the Hubble Space Telescope was launched. It mainly aims in the observation of the universe and the place from where the elements that make up the space has emerged. After the discovery in 1990, the observations made by this is about 1.3 million.
It is considered to one of the most important and a useful instrument that has been discovered. It only revolves around the earth and takes the images of stars,planets and other galaxies without reaching them. The mechanism of optics and detectors that more sensitive in nature are attached to this instrument.
The expression of certain genes at different levels may cause color variation in the butterfly wings.
<h3>What is gene expression?</h3>
Gene expression is the cellular process associated with the transcription of certain genes in particular cell types.
In this case, the trait color in butterfly wings is associated with the differential expression of certain genes during development.
The variation in color may be due to the expression of different alleles in butterflies or the same allele at different levels.
