Answer 2

When the offspring of a pure-bred black guinea pig and a pure-bred white guinea pig were mated among themselves, there were 271 black and 89 white offspring in the F2 generation. This means that the black hair color in guinea pigs is due to a dominant allele.

What is a dominant allele?

A dominant allele is an allele that expresses itself in a cross between two individuals.

• There are two types of alleles, namely dominant allele, and recessive allele.
• Dominant allele expresses itself whereas recessive allele characters are hidden in its gene and tend to express at any point of the future offspring.
• This cross mentioned is a mono hybrid cross because only one trait that is the coat color of the guinea pig is taken into consideration.

Since the majority of the offspring were of black coat, option dominant allele is the right answer.
