Question

2. Incomplete dominance is seen in snapdragons. The allele that causes red flowers (F) is not completely dominant over the allele that causes white flowers (f). When a plant is heterozygous for the trait of flower color (Ff), pink flowers results. Cross two pink snapdragons, and provide the genotypic and phenotypic of all the offspring.

3. Two black guinea pigs were mated and produced 29 black and 9 white offspring. What were the genetypes of the parent guinea pigs? What are the expected phenotypic and genotypic ratios of the offspring?

Explanation / Answer

2) let the parents be heterozygous codition (Ff) * (Ff)

It will produce 4 gamets.

(a) FF - red colour..

(b) Ff - pink colour (incomplete dominance)..

(c) Ff - pink colour (incomplete dominant)..

(d) Ff - white colour..

So in this case the genotype and Phenotype ratio remains the same.. 1:2:1..!!

3) the genotype will be.. B- black dominant,, b-white recessive

BB- homozygous dominant.

bb- homozygous recessive..
