QUESTION 1 In cucumbers, warty fruit (W) is dominant to smooth fruit (w) and dull fruit (D) is dominant to glossy fruit (d). The W gene and the D gene are on the same chromosome and the distance between the two genes is 16 m.u. The S gene controls plant height and is on another chromosome. The dominant allele (S) gives rise to tall plants and the recessive allele (s) gives rise to short plants. Fill in the expected proportions of progeny for each phenotypic group in the table when a plant of the genotype given below is testcrossed to a homozygous recessive plant: Phenotypes warty, dull, tall (W,D,S) warty, dull, short (W,D,s) smooth, glossy, tall (w,d,S) smooth, glossy, short (w,d,s) warty, glossy, tall (W,d,S) warty, glossy, short (W,d,s) smooth, dull, tall (w,D,S) smooth, dull, short (w,D,s) W D S W d s % of Progeny

In cucumbers, warty fruit (W) is dominant to smooth fruit (w) and dull fruit (D) is dominant to glossy fruit (d). The W gene and the D gene are on the same
chromosome and the distance between the two genes is 16 m.u. The S gene controls plant height and is on another chromosome. The dominant allele (S) gives
rise to tall plants and the recessive allele (s) gives rise to short plants. Fill in the expected proportions of progeny for each phenotypic group in the table when a
plant of the genotype given below is testcrossed to a homozygous recessive plant:
Phenotypes
