False, Darwin was just the most famous one to do it.
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.

Answer: Since it's the DOMINANT allele that means that it will take over reccesive allele that's why it's shown.
Explanation: A heterozygous individual is an individual where the have both the dominant and reccesive allele for a trait. The dominant allele will always be stronger than the reccesive allele. This results in the dominant allele being shown.
What he did was say that evolution happened that over time the birds seemed to be changing
