Summary Introduction
Introduction:
Gregor Mendel gave the law of independent assortment in the 19th century. This law states that alleles (forms of genes that are inherited) separate independently during cell division or gamete formation. This he proved by performing breeding experiments on pea plants.

Gregor Mendel proposed the law of independent assortment based on the observation that dihybrid crosses of heterozygous individuals produced progeny in a 9:3:3:1 ratio. For this observation to hold, which assumption must be true?
A. The traits are governed by genes on different chromosomes.
B. The traits are governed by genes on the same chromosome.
C. The traits are governed by genes with only two alleles.
D. The traits are governed by genes with only three alleles.
Which of the following is evidence that Mendel had that helped him to construct his Law of Segregation?A) His F2 generation in the dihybrid cross resulted in a 1:1:1:1 distribution of phenotypes.B) He found no linkage of different genes in the offspring of his pea plants.C) The F1 generation of the monohybrid cross resulted in blended phenotypes.D) The F2 generation of the monohybrid cross resulted in the recessive trait reappearing as a phhenotype.E) Two of the above are correct.
All of the following are reasons that Mendel chose the pea plant as a model system for his studies EXCEPT ________.
A) peas have a relatively short generation time
B) peas produce large numbers of seeds
C) he could control which parents were involved in mating
D) peas only reproduce by cross-fertilization

- c . Mendel's Law of Independent Assortment required us to flip coins separately for each trait.

A. Yes, because human height is a continuously varying trait, just like the traits Mendel studied in pea plants. B. No, because the generation time in humans is relatively long compared with pea plants. C. Yes, because the principles of segregation and independent assortment also apply to human genes. D. No, because human height is not genetically determined.arrow_forward
