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).

Two grizzly bears are fighting over a fish to feed themselves. what kind of interaction is this scenario, which works as a limit

faust18 [17]

Answer: The correct answer is- Intraspecific competition.

Intraspecific competition can be described as an interaction in a population where members belonging to the same species compete for a limited resource ( such as food, water).

As per the information given in the question, both organisms ( grizzly bears) belong to the same species and competing for fish, which is food for them.

Thus, it is an example of Intraspecific competition.
