Answer:
Option (b).
Explanation:
The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.
The heterozygote frequency can be calculated by the formula:
F = 
Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.
Put the values in the above formula
0.3 = 
H = 0.36 ≈ 0.34.
Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.
Hence, the correct answer is option (b).
<u>Answer</u>: Sperm cell
<u>Explanation</u>:
Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.
- A <em>somatic</em> cell is the one which forms the body of an organism and contains all the genetic information.
- A <em>gamete</em> is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
- A Sperm cell is basically a <em>male gamete.</em> It contains only half the amount of genetic information as the other half is contributed by the female gamete.
- This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
- During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the <em>complete genetic information</em>.
- During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each <em>with half the amount of genetic material </em>as present in the parent cell.
Since, <em>sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.</em>
Answer:
four
Explanation:
Carbon atoms have four electrons in their outer shell. So, it exhibits tetravalency & thus, a single carbon atom can form a maximum of four (4) bonds with other atoms

Answer:
gDNA = "genomic DNA" and cDNA = "complementary DNA." cDNA is classically associated with being reverse transcribed either from all extracted RNA from a tissue or cell (total RNA) including (in eukaryotes) pre-mRNA, ribosomal RNA, tRNA, snoRNA, miRNA and mRNA, etc.) while cDNA obtained only from reverse transcription of the mRNA (expressed eukaryotic cytosolic mRNA) fraction (e.g., by poly[dT]n and random priming) is complementary DNA (cDNA) made from what is called the "transcriptome." Eukaryotes have introns and exons in the gDNA, while prokaryotes do not. So eukaryotic cDNA reverse transcribed from mRNA lacks introns. Prokaryotic-derived cDNA is always complementary to prokaryotic RNA and gDNA (so is always necessary to have a good DNase treatment prior to gene expression analysis by e.g., qPCR for prokaryotic transcriptome work)...
