Parent 1 has brown fur. Brown is a dominant color. Parent 1 genotype is Bb. Parent 2 has yellow fur. Yellow is a recessive color. Parent 2 genotype is bb. What is the probability that an offspring has two dominant alleles? Create a Punnett square to help you.

0

Explanation:

In this cross, brown fur (B) is dominant to yellow fur (b).

Parent 1 has brown fur, and a genotype Bb. Parent 2 has yellow fur, and a genotype bb.

The cross is Bb x bb

                       B                     b

      b              Bb                   bb

      b              Bb                   bb

50% of the offspring are heterozygous, and have brown fur (Bb). 50% of the offspring are h0m0zygous for the recessive allele (bb). However, it is not possible for the offspring to have two dominant alleles (BB) from this cross, so the probability is 0.

answer; i believe that the correct answer is; ///bodies of water store heat during the day and release it at night;

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
