Question

What does it mean if there are two different alleles for a trait?

Answer 1

If there are two different alleles for a trait, this means the trait could show up in two different forms.

Answer 2

Answer:

The correct answer would be B. The trait could show up in two different forms.

Alleles refer to the alternative forms of the gene. Different alleles of a gene code for different traits in an organism.

For example, T codes for tallness and t codes for a dwarf. Similarly, R codes for round seed shape and r codes for wrinkled seed shape et cetera.

Based on the expression levels, the alleles can be of two types recessive and dominant.

The allele which expresses itself in a heterozygous condition is said to be a dominant allele and the allele which is masked in heterozygous condition is said to be a recessive allele.
