Question
Polygenic traits produce a wide range of phenotypes.
- True
- False
Hint:
Polygenic trait is a trait in which the phenotype is controlled by more than one gene creating more number of phenotypes.
The correct answer is 'True'.
- When compared to genotype, which is an organism's genetic makeup and the particular combination of genes and alleles present, phenotype refers to an organism's physical or behavioral characteristics.
- People receive their qualities through genetic inheritance.
- Each and every diploid creature receives two sets of chromosomes, one from each parent - the maternal set and the paternal set.
- Each human has 23 chromosomes inherited from their mother and 23 chromosomes inherited from their father.
- Homologous chromosomes are the complimentary copies of each chromosome.
- Numerous genes can be found on each chromosome, and these variations are known as alleles.
- Phenotype describes how those alleles interact with our environment to produce our observable traits.
