Answer: Codon

Explanation: A codon is a triplet of nucleotides in an mRNA that codes for specific amino acids. There are 64 possible codons. They are called the genetic codes. Three of these codons (UAA, UAG, UGA) do not code any known amino acid and are thus called termination codons. One of the codons (AUG) signals the beginning of translation and is thus called initiation codon.

Nimfa-mama [501]

Answer:

100%

Explanation:

No matter how many factors are in the cross, if an 2 purebred (homozygous individuals) are crossed, (one dominant, one recessive) the dominant phenotype will always be displayed.

Imagine a cross with between two individuals true breeding for 6 traits. One shows all dominant genotypes, one shows all recessive genotypes. The only gametes those individuals can pass on will always produce heterozygotes.

AABBCCDDEEFFGG x aabbccddeeffgg

The first individual can only give ABCDEFG alleles. The second individual can only give abcdefg alleles. Therefore, all offspring will be AaBbCcDdEeFfGg, and will therefore express the dominant trait.

<h2>Hypomorphic allele</h2>

Explanation:

  • Hypomorphic Alleles : A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
  • The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."

What percent of the sunlight is actually converted into chemical energy via photosynthesis?
kirill115 [55]

Photosynthesis is a process in which green plants and few organisms use sunlight to synthesize their food from carbon di- oxide and water. In plants, during photosynthesis, green pigment known as chlorophyll is involved and oxygen is generated at a by product.

All the sunlight falling on plant is not absorbed. Only half of the falling light which lies in the right frequency to power photosynthesis is absorbed. Out of this falling light, only 8 % to 11% is absorbed by the plant and only 3 % to 6 % is actually used to form chemical energy.
