Fitness.
Explanation:
Fitness is a relative thing.A genotypes' fitness include its ability to survive,find a mate,produce off spring.
The three ways in which drugs affect the synapses include; they affect the number of neurotransmitters available, the rate of release of neurotransmitters, and binding affinity of neurotransmitter receptors to the neurotransmitters. For example; Drugs can affect the production of neurotransmitters, movement of neurotransmitters into vesicles, or movement of vesicles to a synapse.
Answer: ½ Rr (pink) ½ RR (red) b. rr × Rr gametes: Rr: ½ R, ½ r rr: all roffspring: ½ Rr (pink) ½ rr (white) c. RR × rr gametes: rr: all r RR: all Roffspring: all Rr (pink) d. Rr × Rr gametes: Rr: ½ R, ½ r for each parent offspring: ½ Rr (pink) ¼ RR (red) ¼ rr (white)
Explanation:
Organisms that are well adapted to live together to in the same area over time.
Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
