Figure 5.1 shows the chromosomes in a body cell of a fruit fly. Figure 5.1 Use Figure 5.1 to complete the sentences about the genetic material in fruit flies. The nucleus in a body cell of a fruit fly contains pairs of chromosomes. A cell with a pair of each type of chromosome is known as a Before body cells divide by...

The Rhesus (Rh) factor is a protein that is found on the surface of red blood cells in some people. If the protein is present then the individual is Rh positive. The allele for the presence of the Rh factor is dominant and is represented by the letter D. The recessive allele is represented by the letter d. If a mother...

What examiners said
Comprehensive responses • Many candidates were able to identify the number of pairs of chromosomes in the fruit fly cells and state the name of the type of cells. • Many candidates could also describe mitotic cell division. Limited responses • Some candidate identified two pairs of chromosomes in the fruit fly cells rather than four. • Some candidates stated the cell type as daughter, haploid or...
— Examiner report, February/March 2026, 0610/42 Q5(b) (Cambridge)
Most candidates completed the Punnett square although some used incorrect genotypes for the gametes. The error carried forward principle was applied when this happened. Candidates should use the letters for the alleles given in the stem of the question. The alleles given were D and d. Some candidates used R and h instead, which suggests two different genes are involved in controlling the Rhesus bl...
— Examiner report, May/June 2023, 0610/43 Q5(c) (Cambridge)
Few candidates correctly stated mitosis. There were a wide range of incorrect answers suggesting candidates were unfamiliar with mitosis.
