The relation between genotype and environment in determining the
Introduction:
The genetic composition determines the morphology and physiology of an organism. However, the environment may also affect the phenotype of the organism. The phenotypic variations are an essential part of the evolutionary process of natural selection.

Draw a Punnet square indicating the F2 genotypes from the mating of an F1 male (QQBbHh)
with an Fi female (QQBÜHH).
Note: Make sure to write all the heterozygous genotypes as Gg, not gG.
State the MOST COMMON D positive genotype in both Fisher-Race and Wiener notations.
Consider the MN blood system in humans. This blood system consists of only two alleles, M and N, and they are codominant to each other. Three genotypes are possible, and these genotypes can be easily identified through simple blood typing procedures, including the heterozygous MN due to the codominant mode of inheritance. Consider the following data:
Phenotype
Genotype
Number of individuals
M
MM
89
MN
MN
162
N
NN
79
1. How many alleles exist in this population?
2. What is the genotypic frequency of the M blood type in the population?
3. What is the allelic frequency of M?
4. What is the allelic frequency of N?
5. What is the genotypic frequency of MN?

Two alleles LM and LN determine the M, N, and MN blood groups. The dominant allele R of a different gene causes a person to have the Rh+ (rhesus positive) phenotype, whereas the homozygote for r is Rh− (rhesus negative).
