Describe one similarity and one difference between the two terms in each of the following pairs: monohybrid cross, dihybrid cross. heterozygous, homozygous. genotype, phenotype.

Monohybrid cross is the cross between two individuals where only one of the character or trait is considered while in the dihybrid cross there are two distinct traits that are considered to be cross and studied. The rest of the process is similar in both processes.

Heterozygous is the condition where an individual has two different alleles for the same trait in which one is dominant or other is recessive more often while in homozygous the alleles are responsible for similar traits and characters. Both types shows a similar type of gamete formation and assortment.

The genotype is the set of genes that an individual carries while phenotype is the physical or observable characteristics. Differences in genotype can be responsible for producing different phenotypes.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

thinking it would be d not too sure but i think it's right
