Answer: The correct answer is- B) The dominant allele determines the trait.

Allele can be described as an alternative form of a gene. It exists in two forms that is dominant and recessive allele.

Dominant allele (depicted by capital letter) is the one that masks the expression of recessive allele (depicted by small letter) .

Thus, dominant allele determines a trait (such as Tt for tall pea plant) that is a particular characteristic of an organism.

The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.

<h3>What is heterozygosity?</h3>

Heterozygous means an organism which has two different alleles of a given gene.

An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;

L represents short hair (dominant)
l represents long hair (recessive)

Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.

In many ways, a mule is a superior animal to the horse or donkey. Mules are often stronger and can jump higher than either of th

svp [43]

Answer: They are sterile

Explanation:

Mule is a hybrid of male donkey and female horse with different chromosome number and is considered superior to both horse and donkey. Still it is considered as a weak hybrid this is because the mule is sterile which means that it cannot reproduce further.

The mule though is superior in many ways such as it can jump and is strong. The hybrid of mule is not good as it cannot continue its next generations on earth.

They are sterile and so is a weak hybrid.
