D. store genetic information
Answer:
b. form of a gene
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
The correct answer is B.
The humans forearm is much like a bat wing, because all of our tendons and liniments. Although we do not use the structures in the same ways, they are alike.
11 and 12 seem to be right :) For 13, only organisms which are homozygotic for a certain gene (aa) express a recessive phenotype.
14. This dna exchange between the homologous chromosomes is called crossing-over.
15. geneticly linked or coupled, the phenomenon is known as genetic linkage
16. and 17. also seem all right :)
