Answer:
All the offsprings will be black-furred (Bb)
Explanation:
This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.
According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:
BB - B only
bb - b only
Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:
Bb, Bb, Bb, Bb
All Bb (heterozygous) means that all of the offsprings will be black-furred.
From what I have been taught at any point mutations can occur.
<span>Attached to each sugar ring is a </span>nucleotide base<span>, one of the four bases </span>Adenine<span> (A), </span>Guanine<span> (G), </span>Cytosine<span> (C), and </span>Thymine<span> (T). The first two (A, G) are examples of a </span>purine<span> which contains a six atom ring and five atom ring sharing two atoms. The second two (C, T) are examples of a </span>pyrimidine<span> which is composed of a single six atom ring. A </span>base pair<span> is one of the pairs A-T or C-G. Notice that each base pair consists of a purine and a pyrimidine. The nucleotides in a base pair are </span>complementary<span> which means their shape allows them to bond together with </span>hydrogen bonds<span>. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. Hydrogen bonds are not chemical bonds. They can be easily disrupted. This permits the DNA strands to separate for </span>transcription<span> (copying DNA to RNA) and </span>replication<span> (copying DNA to DNA). In our simple model, the entire base pair structure is represented by the single blue rod. Various more elaborate models can be constructed to represent base pairs, including the one above which shows individual atoms and bonds.</span>
