Answer:
3. CABD
Explanation:
The gene mapping refers to providing position to the genes on the chromosomes. The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.
The gene mapping refers to providing position to the genes on the chromosomes.
In the given question to construct gene map:
1. Look for the highest recombination frequency that is 50% between the C and D.
2. Now look for second-highest value and place the gene accordingly.
3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.
Thus, Option-3 is correct.

Answer:
<u>Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.</u>

Answer:
a shared derived trait.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.
All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.
This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.
A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.
