Huntington’s disease is caused by a defect in the genes, and it can be inherited. A. True
Mendel discovered the fundamental laws of inheritance through his work on pea plants. He used around seven plant traits of which, length of the stem was also considered and hybridization between the tall plants (TT) and the dwarf plants (tt) was conducted.
Alleles refers to the alternative forms of a gene. They are the recessive and the dominant alleles. According to Medel's law of dominance, the recessive alleles are masked by the dominant alleles. In pea plants, the allele for tallness is dominant. It expresses itself in both the homozygous dominant condition and the heterozygous dominant condition. Thus, the possible genotypes of a tall pea plant are TT and Tt.
The overall structure is said to be a double helix composed of nitrogenous bases and the sugar backbone. It is also double stranded too
B. I think correct answer
In the first one draw the molecules closer together and in the second one draw them more diverse and farther apart hope that helps
