OBJECTIVES
Define
Give Scientific Reasons
In sexual mode
of reproduction grater diversities are generated.
Phenotypic and
genotypic ratios are different
In human beings
the gametes from the male parent decides the sex of the baby.
Paleontological
evidence suggest that invertebrates came into existence before the vertebrates.
Vermiform appendix of man has become a vestigial organ.
Nowadays in the
surroundings of Birmingham, black moths are found in large numbers.
In F2 generation
of Mendel’s Monohybrid cross the phenotypic ratio is approximately 3 red : 1
white.
The plants of F1
generation of Mendel’s Monohybrid cross are phenotypically red but
genotypically hybrids.
In parental
generation (P1) red flowers were called dominant and white flowers as
recessive.
Answer the following in detail.
With the help of
a diagram (Punnett square) show a Mendelian experiment where tall tea plant
bearing red flower is crossed with a short pea plant bearing white flowers.
Write both the phenotypic and genotypic ratio for F2 generation.
