The offspring are all violet. The genotypeIn a dihybrid cross TtRr × TtRr in pea, the **probability** of producing a homozygous recessive (ttrr) offspri**Phenylketonuria (PKU)** in humans is caused by:**Criss-cross inheritance** of an X-linked recessive trait (e.g. colour blindness) means the gene is transmittIn sickle-cell anaemia, what is the expected ratio of normal : carrier : sickle-cell anaemic children from a mA **carrier woman** (X^c X) marries a **normal man** (X^c Y) for colour blindness. What proportion of their of*Drosophila melanogaster* has 4 pairs of chromosomes. Hence the number of linkage groups in Drosophila is:In Morgan's experiments on Drosophila, genes for **yellow body** and **white eye** showed only 1.3% recombinat
