Which statementbest describes the influence that parents have on whether or not offspring inherit a genetically inherited trait?

A

A) Each parent contributes two chromosomes.

B) Each parent contributes one allele.

C) Each parent contributes two alleles.

D) Each parent contributes one chromosome.

Each parent contributes one allele describes the influence that parents have on whether or not offspring inherit a genetically inherited trait.

Explanation:

Allele is a form of gene present on the chromosome. Human have 2 alleles for a trait on a chromosome. Each parent contributes one of its allele to the progeny. The alleles for the gene are present on the same locus of chromosomes.

The alleles are either dominant or recessive. The contribution of alleles and the expression of trait decide the alleles of offspring.

The phenotype is determined by the allele expressed as short or tall and human ABO blood type.

An allele is sequence of DNA. The organism having two same alleles are homozygous and having two different alleles are heterozygous.
