Answer:
9/16 Kinked tail, normal growth
3/16 Kinked tail, obese growth
3/16 normal tail, normal growth
1/16 normal tail, obese growth
Explanation:
Kinked tail (K) is dominant over normal tail (k) and normal growth (N) is dominant over obese growth (n). Two mice that are heterozygous for both traits (KkNn) are crossed:
KkNn x KkNn
offspring:
<em>9/16</em><em> K_N_ - Kinked tail, normal growth</em>
<em>3/16</em><em> K_nn - Kinked tail, obese growth</em>
<em>3/16</em><em> kkN_ - normal tail, normal growth</em>
<em>1/16</em><em> kknn - normal tail, obese growth</em>

Answer:
cloning
Explanation:
one of the most controversial uses of genetic engineering has been cloning, or producing a genetically identical copy of organism. while the ethics of cloning are hotly debated, the 1st ever sheep was cloned in 1996 by scientists.
Answer:
The correct answer will be option A.
Explanation:
The bacteria organize its genetic material in the single circular chromosome suspended in the cytosol along with additional circular double-stranded DNA molecule called plasmid.
The plasmid is present as a separate structure in the cytoplasm which performs important functions during stressful conditions in the bacteria like providing antibiotic resistance to the bacteria, formation of filial factors during conjugation and many others.
The plasmid which confers resistant to the bacteria is known as the R-plasmid. The R-plasmid consists of r-determinants which confers antibiotic resistance to the bacteria and resistance transfer factor (RTF) which helps in plasmid transfer.
Thus, option A is the correct answer.
Answer:
The answer is the first option.
Explanation:
Farming emerged because being a nomad was no longer suitable for increasing population size. Farming allowed people to stay in one place and properly feed their families, which was a definite positive impact on population size.
