Which of the following is not a part of the DNA molecule?

Mendel explained that alleles assort independently. Assume that instead of independent assortment, the inheritance of one allele affected the inheritance of others. If you cross individuals that are AaBb, and the inheritance of a dominant allele at the “A” gene locus requires the inheritance of the dominant allele at the “B” gene locus. What is the expected phenotypic ratio for this cross? What are the possible gametes produced by each individual? What is the probability of each gamete?

Consider a chromosome that contains three linked genes A, B, and C. The recombination rate between A and B is 35%, between A and C is 20%, and between B and C is 55%. Which two genes are least likely to assort independently during meiosis?

If natural selection removes harmful genes from a population, why do so many genetic disorders persist?

Explain the Law of Independent Assortment. How is it different than the Law of Segregation?

Mendel also suggested that a gene will only have two alleles and two possible phenotypes, but we know from blood type that there may be more than two alleles, and many phenotypes. In blood type there are 4 phenotypes: “A” from being either homozygous A or heterozygous AO, “B” from being homozygous B or heterozygous BO, “AB” from having both the A and B alleles, and “O” from being homozygous O. a cross between which of those genotypes would make all phenotypes possible?

The color of the human eye is controlled by two gene loci. The first locus determines whether the iris will be brown, green, or hazel (brown and green). The second locus determines whether the brown or green color will be expressed. If the gene inhibits the expression of color, the eye is blue. Which of the following best explains the equal, but separate expression of the brown and green pigment in hazel eyes?

Which of the following is an enzyme that lengthens the RNA primer by applying new DNA nucleotides?

What is the genotypic ratio in a cross between individuals that are heterozygous (Aa) for a gene that shows incomplete dominance?
