Given a parent genotype of Bb, what are the possible gametes that they can produce?
Assuming both parents have genotype Bb, this would lead to the Punnett square (in this case a monohybrid cross) as shown in the image below. We have four outcomes, three of which are unique. Those offspring genotypes are: BB, Bb, and bb.
An offspring with B or b on its own is not possible because both parents contribute genes.

Some organisms have a large geographic range. For example, the Norway rat lives on every continent except Antarctica A population of Norway rats is the number of rats in one particular area. Do you think it's scientifically possible for a population of Norway rats in North America to carry different genetic mutations than a population of Norway rats in Africa? Do you think it's possible that they carry some of the same mutations? What types of information can scientists learn by studying the genomes of these two populations of rats?

What is Earth?Earth is the third planet from the Sun and the only celestial object known to harbor life. Only Earth maintains liquid surface water in the Solar System. About 71% of Earth's surface is made up of ocean, which dwarfs Earth's polar ice caps, lakes, and rivers.
Earth consists of land, air, water and life where land consists of mountains, valleys and flat areas and air is composed of various gases, mainly nitrogen and oxygen. Water includes oceans, lakes, rivers, streams, rain, snow, and ice.
Venus is known as our sister planet because of the similarity in size, mass, density, and volume that both planets are believed to share a common origin at the same time from a condensed nebula about 4.5 billion years ago.
Thus, Earth and Venus are about the same size. So, the correct option is (A).
