Answer:
Density independent limiting factors affects all populations in an ecosystem, regardless of the population size. These include: Natural Disaster (Earthquakes)
Temperature (Extreme Temperatures, summer and winter = two totally opposite temperatures)
Answer:
The correct answer is -
Parental - BB and bb
F1
Genotypes: 100% Bb
F2
Genotypes: ¼ BB, ½ Bb, ¼ bb
Explanation:
It is given that a cross between a brown and a silver-blue mink produces all brown offspring and it is only possible if brown is dominant over silver blue in true breed cross, assume brown trait is represented by B and silver-blue is b then parents will be
BB and bb
B B
b Bb Bb
b Bb Bb
Cross between F1 individuals: Bb cross Bb
gametes : B, b and B, b
B b
B BB Bb
b Bb bb
the genotype of F2 : 1:2:1 = ¼ BB, ½ Bb, ¼ bb
It is the area where the two chromatids of a chromosome attach to each other
Answer:
Recombinant DNA can replace a gene in an animal’s genome.
Explanation:
The molecular cloning process involves in creating Recombinant DNA. This DNA is used to replace or replicate any specific gene. This is done by the process of PCR to replicate it directly.
This formation is done in the presence of a vector. This method is used in the field of veterinary office, pharmacy and many more. It has the ability to replace the gene of an animal’s genome.
