Crossing a BB male with a Bb female:
The Punnett Square will look like this:
BB BB
Bb Bb
The percentage will be as follows:
- You will have 50% homozygous dominant (BB)
- You will have 50% heterozygous (Bb)
Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.
For the genotype, you have 50% BB and 50% Bb
Answer: genotypic ratio 2/4
Phenotypic ratio 4/4 is the same
Explanation: suppose RR is the dominant female and Rr is the heterozygous male. Then after the cross genetically 2 have RR and 2 have Rr ratio. But phenotypically all 4 are the same.
<span>Diet drugs such as lorcaserin and
phentermine-topiramate help people in losing weight by reducing food intake. These
drugs are affecting the central nervous system, which act as an appetite suppressant
where a person will not feel hungry or has lesser urge in eating does reducing

The answer is seeds and pollen. They allow for the free dispersion of plants in terrestrial environments hence allowing plants colonize new habitats. Additionally, the seeds and pollen can remain dormant for a period of time and sprout only in favourable conditions for plant growth
