Multiple Choice

In fruit flies (Drosophila sp.), the long-winged flies were self-mated. Out of 520 offspring, 130 had short wings while the remainder has long wings. The allele for long wings is dominant (W) and allele (w) represents short wings. Which is the correct pair of genotypes of the parents?

• Ww x ww

• Ww x Ww

• WW x ww

• WW x Ww

Dihybrid inheritance involves inheritance of two characteristics, each characteristic is controlled by a .................. located at a different locus.

Open Ended

Diagram shows the inheritance of body colour and size of wing in Drosophila sp.

G represent the dominant allele for grey body while g represent the recessive allele for black body.

N represent the dominant allele for normal size wing and n represent the recessive allele for big wing.

State the phenotype of A.

Multiple Choice

Law of Independent

Assortment (Mendel's Second Law) states;

• During gamete formation, each allele from a pair of alleles can combine randomly

  with any allele from another pair of allele.

• A characteristic of an organism is controlled by a pair of

  alleles, and only one of the allelic pair is inherited in a gamete.
