Answer:
Please find how this is possible in the explanation below
Explanation:
This question is regarding a gene in rabbit coding for fur color. Brown fur (B) in rabbits is dominant over white fur (b). However, according to the question, a white female gives birth to all white rabbits, even though the father had brown fur. This is possible because the father is heterozygous for the brown fur i.e Bb.
Hence, in a cross between a heterozygous father (Bb) and a white mother (bb), the following gametes will be produced by the following parent:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the probability of 1/2 of the offsprings will possess white fur (bb). Based on this result, the white female is able to give birth to all white rabbits because the male rabbit contributed the white allele (b).
What are the answer choices?
DNA Base pairing rules are A pairs with T and C pairs with G. Therefore, if one strand of DNA has the sequence ATG, the complementary strand would have the sequence TAC.
Answer:
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem.
