Two short-haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable gen
Alekssandra [29.7K]

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.

If a species has 35 percent adenine in its dna, what is the percentage of the other three bases?
Basile [38]

Answer:

The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.

Explanation:

There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.
