Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
Question
Transcribed Image Text:Gametophytes of the C-fern were described in Table 1 (p.
281) and their sporophyte offspring were described in
Table 2 (p. 282). The following questions are based on the
class data totals.
1. What was the proportion (frequency or
percentage) of the dominant and recessive alleles in
the gametophyte generation?
2. What was the proportion (frequency or
percentage) of the dominant and recessive alleles in
the sporophyte generation?
3. Using Hardy-Weinberg Equilibrium equation, what
are the expected genotypes of the sporophyte
generation in Hardy-Weinberg Equilibrium based
on the population of the gametophytes?
4. Was this population in Hardy-Weinberg
Equilibrium? If so, why is that expected? If not, what
possible reason could explain the results?
