Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.
Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, <span>the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, </span><span>amino acids are paired with anticodons, gradually forming a long chain</span>; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.

The sensory input initiated from the spinal cord before reaching to the brain . The information firstly goes to first order neuron where it receives impulses from skin and then transferred to the spinal cord.
Some sensory pathways consists of chain of neuron that transfer from receptor organ then to cerebral cortex that is responsible the perception of sensations. Sensory input is converted into electrical signals are known as nerve impulse.
This nerve impulse are transmitted into into brain. The correct order is Receptors - Sensory neuron- Spinal cord - Motor neuron- Muscle.
Impulse are the strong desire to act or that causes something to happen or happen more quickly.
