Question

Which statement correctly describes the mechanism of inheritance?

Alleles from heterozygous chromosomes determine traits.

Chromosomes on homozygous genes determine traits.

Alleles on homologous chromosomes determine traits.

Homologous chromosomes determine the genes for a trait.

Answer 1

Alleles on homologous chromosomes determine traits.

Answer 2

• The statement that alleles on homologous chromosomes determine traits, correctly describes the mechanism of inheritance.

• Homologous chromosomes are defined as a pair of chromosomes which have the genes arranged on them in the same order however the alleles may be different.

• The chromosome pair of homologous chromosomes is formed because a diploid organism has one paternal and one maternal chromosome, and when these 2 chromosomes pair together we get a homoglous chromosmes.

• The variants of a particular gene present on the chromosome are known as alleles.

• The combination of the alleles transferred from the parents to the offspring is responsible for the inheritance of traits.
