Explain why Mendel needed only 1 character / set of traits to explain the Law of Segregation, yet needed 2 characters / sets of traits to explain the Law of Independent Assortment.

In a dihybrid cross of two bi-allelic Mendelian genes, A (two alleles – completely dominant A and recessive a), and B (two alleles – completely dominant B and recessive b), such that the parental generation comprises of pure-bred homozygotes (i.e. AABB with aabb), what are the expected genotype and phenotype ratios in the F1 and F2, if the F1 cross is (a) an intercross and if the F1 cross is (b) a testcross

How do some differences in the outcomes for sets of gametes produced illustrate Mendel's laws of independent assortment and segregation? Be brief and specific.

Mendel’s experiments used plants that had traits which follow simple laws of dominance, segregation, and independent assortment. We have since learned that not all traits follow these simple laws. Give at least three examples of non-Mendelian inheritance patterns and explain how each differs from Mendel’s laws of inheritance.

In Mendel’s law of segregation, a diploid cell has select answer copies of every gene that occur on its homologous chromosomes. Alleles at any locus are distributed into separate gametes during meiosis. Collectively these statements make up Mendel’s select answer .

In one of his experiments, Mendel crossed homozygous yellow plants with homozygous green plants. The resulting F1 generation was allowed to self-fertilize. The F2 generation produced 930 yellow seeds and 305 green seeds. What are the genotypes of this F2 generation? O YY : yy O Yy : yy O Yy: yy O YY: Yy : yy

When Mendel did his experiments, it was the case that the genes for each trait were on separate pairs of homologous chromosomes. For example, the genes for pod color were on one pair of chromosomes and the genes for the seed coat were on a different pair of chromosomes. What if the genes for the two traits were on the same chromosome? (That is, if the gene for pod color was on the same chromosome as the gene for seed coat.) Would Mendel’s 2nd Law still hold? Why or why not?

Part 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel's Principle of Segregation. Use two parents with homologous chromosomes marked with alleles "A" and "a". Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel's Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Part 3: Use homologous chromosomes marked with alleles "A" and "a" and a second pair of homologs marked with alleles "B" and "b". to demonstrate Mendel's Principle of Independent Assortment in cells in Meiosis. Indicate what phase this…

What is the hypothesis that Mendel's laws are based on?
