Answer:

Explanation:

I wonder who makes these questions sometimes. It can also be proven false.

I guess you should answer true, but I'd be careful about what the accepted answer is. A hypothesis can be proven true. If you were going to try and prove that rain water is part of the water cycle, you could devise a test that would show it to be true.

It is based on an educated guess and it is a flat statement, not a question.

Rainwater is part of the water cycle.

Would be an example.

In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessiv

ValentinkaMS [17]

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.
