some heterozygous alleles create variations in expression so that there is not a clear dominant or recessive allele true or fals
Simora [160]

Answer: False

 The variations in expression depends on how genes code for proteins that would specify whether it will be dominant or recessive allele.   Within a population, there may be a number of alleles for a given gene and these differences can cause variations in the protein that is produced. The change in protein expression affect traits due to the variations in protein activity or expression that produce different phenotypes.

<span>Moreover, individuals that have copies of different alleles are known as heterozygous and individuals that have two copies of the same allele are referred to a homozygous. The expression patterns observed in inheritance will depend on whether the allele is found on an autosomal chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>

MrRissso [65]

Answer:

c. have changed the behavior of elk.

Explanation:

Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.

The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.
