Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).

Answer:
100% merle with long coats.
Explanation:
<em>All the offspring produced from the cross would be merle with long coats.</em>
<u>From the illustration:</u>
Merle gene is represented by the genotype cmcs.
fgf5 gene determines the coat phenotype. Let the gene be represented by the allele A. A determines long coat traits and it is dominant over its alternate form, b, which determines short coat trait.
Now, two merle (cmcs) dogs were mated. One is true-breeding for long coat (AA) while the other is true breeding for short coat (aa).
cmcsAA x cmcsaa
Progeny genotype = cmcsAa
cmcsAa = merle with long coat.
<em>Since </em><em>A</em><em> is dominant over </em><em>a,</em><em> all the progeny from the cross will be merle with long coat.</em>
