Zorluk: OrtaBasic Genetics Terminology and Concepts

Match each basic genetics term on the left with its corresponding definition on the right.

  • Gene locusThe specific physical position of a gene on a chromosome
  • AlleleAlternative molecular form of a gene located at a specific position on homologous chromosomes
  • PhenotypeThe observable physical and physiological expression of an organism's genetic makeup
  • HomozygousThe condition of possessing identical alleles for a given gene on homologous chromosomes

Cevap

Gene locus matches the specific physical position of a gene on a chromosome; Allele matches alternative molecular form of a gene located at a specific position on homologous chromosomes; Phenotype matches the observable physical and physiological expression of an organism's genetic makeup; Homozygous matches the condition of possessing identical alleles for a given gene on homologous chromosomes.
Each genetic term correctly pairs with its fundamental biological definition: Gene locus is the physical chromosome position; Allele is an alternative form of a gene; Phenotype represents observable expressed characteristics; Homozygous describes having identical alleles for a specific gene.

Adım Adım Çözüm

1
Identify the definition of gene locus.
Gene locus corresponds to the specific physical position of a gene on a chromosome.
The term 'locus' originates from the Latin word for place, denoting the specific site of a gene on a chromosome.
2
Identify the definition of an allele.
Allele corresponds to an alternative molecular form of a gene located at a specific position on homologous chromosomes.
Genes often exist in multiple variant forms called alleles that dictate alternative versions of a trait.
3
Identify the definition of phenotype.
Phenotype corresponds to the observable physical and physiological expression of an organism's genetic makeup.
Phenotype is the external manifestation of genetic instructions combined with environmental influence.
4
Identify the definition of homozygous.
Homozygous corresponds to the condition of possessing identical alleles for a given gene on homologous chromosomes.
The prefix 'homo-' means same, indicating identical genetic alleles present at a particular locus.
