1. What kind of assortment does the F2 generation exhibit? Which of Mendel’s laws does it support? 2. What are the genotypes of both of the first parent plants? 3. Why do the F1 generation plants only contain tall plants with red flowers? Why are there no short plants or white flowers? 4. According to the activity, what is the genotype for the F1 Generation? What is their phenotype? 5. From the Punnett Square, what is the ratio of short-white...

In this tutorial you will examine dihybrid crosses: crosses
where alleles at separate loci assort independently into gametes at
meiosis. You will also use logic to determine unknown genotypes,
phenotypes, and genetic ratios from given data.
Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele...

2. You carry out a dihybrid cross in sweet peas where you examine the flower color locus (use symbols based on "P" for this gene) and blooming time locus (use symbols based on "L" for this gene). You cross a true breeding purple- flowering, early blooming plant to a true breeding red-flowering, late blooming plant. The F1 plants are all purple- flowering and late blooming. The F1 plants were subsequently used in a testcross. The flower color locus and the...

Given the genotype AaBbCcDdEE a) How many kinds of gametes can this individual form? b) If selfing occurred, what fraction of the progeny would have the following genotype: AaBBccDdEE? A cross between two plants produces progeny which, through subsequent breeding experiments, are shown to fall into 27 genotypic classes. Assuming that complete dominance operates at all of the loci involved and that each locus has two alleles, a) At how many different loci are the parents heterozygous? b) How many...

How many different combinations of alleles are possible among the gametes produced by an individual that is heterozygous for 5 separate (unlinked) genes? five ten sixteen thirty- two Consider a pea plant heterozygous for two dichotomous traits. flower color: PP and P_p = purple flowers; pp = white flowers. seed shape: RR and Rr = round seeds; rr = wrinkled seeds. A self-hybridizing dihybrid plant (PpRr x PpRr) generates F2 seeds that can be planted to grow into plants (di-hybrid...

Hello, I just need someone to check my answer: The answer I choose are in bold points. 1. What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? Recessive genes occur more frequently in the F1 generation than do dominant ones Traits are inherited in discrete units, and are not the results of "blending" There is considerable genetic variation in garden peas Genes are composed of DNA 2. In a particular plant, two genes...

(1) One of the standard techniques to determine whether two loci are physically close to one another on the same chromosome is to conduct a "dihybrid cross", a cross of two individuals that are heterozygous at both loci. For example if the two loci have alleles A and a at the first locus and B and b at the second locus then crossing...
