In horses, B= black coat, b= brown coat, T= trotter, and t= pacer. A black trotter that has a br

step 1 And we've got black coat is dominant to brown, and trotter is dominant to pacer. So a black trot

a. $B T$
b. $B b T t$
c. $b b t t$
d. $B B t t$
e. $B B T T$

Key Concepts

Heterozygosity

Heterozygosity refers to having two different alleles for a particular gene. In cases of dominant-recessive relationships, a heterozygous genotype shows the dominant phenotype, while still carrying the recessive allele that may be transmitted to offspring.

Genotype

Genotype refers to the specific allelic composition of an individual for one or more traits. It encompasses both dominant and recessive alleles, and understanding genotype is crucial for predicting and explaining patterns of inheritance in offspring.

Phenotype

Phenotype is the set of observable traits or characteristics of an organism, resulting from the interaction of its genotype with the environment. It provides the basis for deducing underlying genotypes, especially when dominant and recessive alleles are involved.

Dominance

Dominance is a genetic concept describing how one allele (the dominant allele) can mask the presence of another allele (the recessive allele) in a heterozygous individual. This explains why an organism can express a dominant phenotype even if it carries a recessive allele.

Dihybrid Cross

A dihybrid cross is used in genetics to study the inheritance of two different traits simultaneously. It employs the principles of independent assortment and segregation to predict the distribution of genotypes and phenotypes among the offspring.
