Respuesta :
The correct option is B.The chromosome is a thread like structures, which is made up of nucleic acid and protein. It is usually found in the nucleus of living organisms and it normally carries genetic information in form of genes.
Answer:
The correct answer is B. allele
Explanation:
Alleles are the multiple forms of a single gene that can be inherited into the next generation. A gene can contain multiple alleles like for height we have 2 alleles one for short height and one for long height.
Some genes have more than 2 alleles like in case of blood group we have 3 alleles of a gene A, B, and O. Some alleles are dominant and some are recessive. Dominant allele repress the expression of recessive alleles.
Allele from two different genes are independently assorted during the gamete formation. The homozygous chromosome contains the same gene set in the same sequence that may contain identical or non-identical allele.
Therefore, allele is the inheritable form of a single gene so the correct answer is C.
