The genotype for a mouse that has curly hair and is heterozygous for tail length is hhTt. The correct option is A.
What is a genotype?
Genotype is the genetic material of an organism that is present in the nucleus of the cells of the organism. Its other name is allele or gene or variation.
Here, the mouse has two types of genes; Straight hair (H) is dominant and curly hair(h). They also have two types of genes for Short tails(T) are dominant to long tails(t).
So, the genotype of the mouse for curly hair h and heterozygous for the tail, which means it can be short or long, will be hhTt. hh, which represents the curly hair that is specified. And the T is for the short tail, and t is for the long tail. So it becomes heterozygous.
Thus, the correct option is A. hhTt.
