Detailed explanation-1: -It was concluded that the shape of leaf tip is under the control of two genetic loci with duplicate genes interaction without cumulative effect. In that case obtuse shape of leaf tip is a double recessive homozygote.
Detailed explanation-2: -One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
Detailed explanation-3: -During this time, Mendel observed seven different characteristics in the pea plants, and each of these characteristics had two forms (Figure 3). The characteristics included height (tall or short), pod shape (inflated or constricted), seed shape (smooth or winkled), pea color (green or yellow), and so on.
Detailed explanation-4: -The parent plant’s genotype is simply the known allelic constitution of the parent plant’s genes. For example, if one parent plant has a genotype of BB and the other parent plant has genotype bb then the progeny plants will all be of genotype Bb.
