Chapter 15, Problem 1FIB
Summary Introduction

Introduction:

The Hardy-Weinberg principle states that “allele and genotype frequencies” are remaining constant in a population, from one generation to the next. In a given population, if the gametes donated randomly to the next generation, would lead to unchanged allele frequencies.

Answer to Problem 1FIB

Correct answer:

The Hardy-Weinberg principle provides a simple mathematical model for a non- evolving population, also called an equilibrium population, in which allele frequencies do not change over time. No such populations are not likely to be found in nature.

Explanation of Solution

The Hardy-Weinberg principle defines populations which are no longer evolving, and known as “equilibrium populations”. This type of populations does not consider changes in “allele distribution” from one generation to the next generation. This principle applies only when evolution does not occur in a population.

According to this law, “allele and genotype frequencies” in a population remain constant from “generation to generation”. In a given population where gametes contribute to the next generation randomly, allele frequencies will not change. This law is “not” applicable on “real population”.

Conclusion

The Hardy-Weinberg principle defines about “genotype and allele frequencies” that remained constant from one generation to the next.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW).  If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?
None
Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
