Answer:
The Genotype of an organism determines the genetic characteristics of an individual.
 If a father produces sperm that carry only 't' alleles, the his genotype will be 'tt' or hom.ozygous genotype.
Hom.ozygous genotype contains the same type of genes responsible for a particular phenotype.
Hence, the correct answer is 'tt' or hom.ozygous genotype.

A biodiversity hot spot is a relatively small region with a significant number of indigenous species and endangered or vulnerable species.
Ecologically distinct areas with extraordinarily high species densities are known as biodiversity hotspots, and they are thus top priorities for nature conservation. The term "biodiversity" has several meanings. A species area must satisfy two severe requirements in order to be considered a biodiversity hotspot: It must have a significant proportion of plant life that is endemic, or found nowhere else on the earth, and at least 1,500 vascular plants. In other terms, a hotspot is unique.
