Answer:

A statement can contain one argument, more than one argument or no argument.

Argument are intended to determine the degree of truth hence enabling a conclusion to be made. It contains one or more premises and only one conclusion.

A premise is the statement in the argument that provides reasons to support a conclusion.

In the first statement, there is no argument. This is because there is neither a premise nor a conclusion

The second statement has a conclusion(the last sentence) and two premises(first two sentences) therefore it is an argument.

Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable gen

Answer:

Ss (male) × Ss (female)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".

According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1

To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.
