A pea plant bearing axial flower is crossed with a pea plant bearing terminal flowers. The cross was carried to find the genotype of the pea plant bearing axial flowers. Work out the cross to show the conclusions you arrive at.
Answers
Answer:
(i) If the plant is homozygous for the dominant trait
AA. * aa
(axial ). ( terminal)
Aa Aa Aa Aa
all plants are at axial..
(ii) If the plant is hetrozygous for the dominant trait
Aa. *. aa
(axial) (terminal)
Aa Aa. aa aa
50% are axial flower and 50% are terminal flower
Conclusion : If all progeny show axial flowers (dominant) the plant is homozygous (AA) , If 50 % of Progeny show Axial flower (Dominant) and 50% Terminal flower (Recessive) the plant is heterozygous
Answer:
if the offspring produced by the test cross is 50% purple and 50% white flower then the genotype of the purple flower pea plant is heterozygous dominant (Pp). If all the flower produced is purple coloured then the genotype of the purple flower is homozygous dominant (PP).
