if you examined the inheritance pattern of two traits found on the same chromosome, would you expect the allele combinations for the gamates produced by to follow Mendel's law of independent assortment? Why or why not?
Homework Answers
Answer:
If the two traits are present on the same chromosome, the responsible two genes do not assort independently due to linkage phenomenon. It means that the two genes are linked and inherited together to the progeny; there would be no crossing over and no independent assortment as mentioned by Mendel.

Mendel crossed pea plants dominant for two different traits tall and green pods) with pea plants recessive for those same two traits (short and yellow pods). This cross resulted in pea plants that had combinations of all four traits tall with green pods, tall with yellow pods, short with green pods, and short with yellow pods).

1. No result of cross was provided. Mendel performed a dihybrid cross to analyze the inheritance pattern of two characters, seed color (Y and y) and seed shape (R and r), in order to determine whether assortment is linked or independent. See the lecture slides for the results of this cross. 1) What would the outcome of his cross be if he found assortment was linked? 2) What would the outcome of his cross be if he found assortment was...

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...

1.2 According to the Mendel's second law, alleles of two different genes assort independent of each other. Thus, the presence of a specific allele at a first locus cannot tell what the allele is at the second locus on the same chromosome. But often times, if we know the allele at the first locus, we can predict that one allele would appear at a higher probability than expected according to Mendel's second law. This type of allelic association is termed

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...
