Imagine you are performing a cross involving garden pea plants. What F1, F2 offspring
would you expect if you cross true-breeding parents with green seeds and yellow
seeds? Yellow seed color is dominant over green.
What will be the appearance of (a) F1 and (b) F2 progenies when a pure (homozygous)
tall pea plant is crossed with a pure (homozygous) dwarf pea plant?
What observations led Mendel to conclude that traits were inherited as particles from
each parent?
Discuss the role the following pieces of evidence played in the making of chromosomal
theory of heredity:
a) The discovery of the white fly.
b) The microscopic evidence for chromosome pair crossing over.
c) The coupling factors on the Drosophila X chromosome.
A cross was made between pure breeding plants differing in
two characters (colour and shape of seed) and the progenies
were inter-crossed to produce F2 population. Four types of
phenotypes; yellow round (1108), yellow wrinkled (382), green
round (366) and green wrinkled (140) were observed in F2.
Outline the significance of the formation of the triplex invasion to potential therapeutic applications.
Describe your understanding of a Hoogsteen pair and the formation of nucleic acid triplex. Is this held together by an intermolecular bond or an intramolecular bond?
As we know that maximum recombinant frequency possible is 50% & in case of linked genes it is less than 50. But in Mendel's experiment in F2 (dihybrid) the recombinant frequency was 37.5% even though the genes were unlinked( on different chromosomes). Why it comes 37.5% and not 50%?
Explain how PNAs could be used to control protein translation. Make specific reference to curricular concepts and vocabulary.
