Here are the solutions to your questions: 7.1 Step 1: Determine the genotypes of the parents. Lindwe is a female, so her genotype is XX. The father is a male, so his genotype is XY. Step 2: Perform a genetic cross (Punnett square). Parents: XX (Lindwe) × XY (Father) Gametes from Lindwe: X, X Gametes from Father: X, Y |c|c|c| & X & Y \\ X & XX & XY \\ X & XX & XY \\ Step 3: Determine the percentage chance of having a boy. Possible offspring genotypes: XX (female), XY (male). From the Punnett square, 2 out of 4 possible outcomes are XY (male). Percentage chance of a boy: (2)/(4) × 100\% = 50\%. 50% 8.1 a) 1 to 22:* Autosomes b) 23:* Sex chromosomes (or gonosomes) 8.2 Male 8.3 Individual P has one X chromosome and one Y chromosome at position 23. The Y chromosome is visibly smaller than the X chromosome. 8.4 One chromosome in a homologous pair is inherited from the mother (maternal origin), and the other chromosome is inherited from the father* (paternal origin).
