Answer: All of the offspring are brown. The chances of getting a brown deer is 100%.
Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.
Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.
To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.

Answer:
The scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
Explanation:
The transcription of the R gene decreases when histone methyltransferase is inhibited, this proves that histone methylation increases the transcription of the R gene.
When the gene is in the condensed state, RNA polymerase can no longer gain access to the region so as to transcribe the R gene. Thus, in order for the gene to be transcribed, the gene has to be in the open (euchromatin) state.
Histone methylation makes the gene in the euchromatin state.
Therefore, the scientific claim that is most consistent with the findings in the question given is that: histone methylation opens up chromatin at gene R, so transcription factors can bind to DNA more easily.
A species must be able capable of surviving and reproducing despite changes to food sources, climate, or threats from predators.
