Answer:

Genotype of  rough coat boar - Rr

Genotype of soft coat sow mate - rr

Explanation:

Rough coat boar must be heterozygous with one dominant allele (R ) and one recessive allele (r )

Genotype of rough coat boar - Rr

Genotype of soft coat sow mate – rr

Now if these two parents are crossed , the offspring produced are represented in the punnet square below –  

R r

r Rr rr

r Rr rr

Thus, 50 % of the offspring’s have rough coat (Rr) and 50 % of the offspring’s have smooth coat.

1. Do a pun-net square.
R r
r
r
2. The offspring would be Rr, rr, Rr, rr
3. 2 of them are heterozygous(Rr),which means they would be most likely rough coats
4. Two of them are homozygous for short hair (rr) which means they are going to be soft hair.
5. Your answer is
Rr, rr

If immigration and emigration numbers remain equal which of these could cause a slowed growth rate
rodikova [14]

Answer;

Decreased birthrate

If immigration and emigration numbers remain equal , decreased birthrate could cause a slowed growth rate.

Explanation;

All populations change in size with time . Change in population is dependent of various factors, namely; birthrates, death rates, immigration and emigration.

Therefore; change in population size would be given by the difference of the sum of birth rates and immigration and the sum of death rates and emigration. That is; Change in Population Size = (Births + Immigration) - (Deaths + Emigration). A decreased birth rate with emigration and immigration remaining constant would cause a slowed growth rate.

<span>
The thickening of the heart muscle may block blood flow out of the ventricle which then must work hard to pump blood. As a result, the symptoms can include chest pain, dizziness or fainting.</span>
