Apea plant exhibits a recessive trait. which statement is most likely true about the plant? the plant is identical to its parent plant. the plant has different alleles for the gene that codes for the trait. the plant has two identical alleles for the gene that codes for the trait. the plant does not have the same genes for the trait as its parent plant.

Ans.

A recessive trait is defined as a trait that gets expressed by an individual, when he shows homozygous recessive condition. This means that a individual showing a recessive trait will possess both the recessive alleles for that trait as recessive trait gets concealed by the presence of allele for dominant trait.

Thus, the correct answer is 'option). the plant has two identical alleles for the gene that codes for the trait' as only then, it will exhibit the recessive trait of that gene.

Pea plant will exhibit a recessive trait when the plant has two identical alleles for the gene that codes for the trait.

Further Explanation:

Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.

A recessive trait is defined as a trait that gets expressed by an individual, when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as recessive trait gets concealed by the presence of allele for dominant trait. So, the pea plant definitely posses two recessive allele for the recessive trait. When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
