3.) 10% is the crossover percentage between two genes that are 10 map units apart because , the percentage of recombination ( crossing over) between two loci is directly related to the physical distance between the loci. 1% crossing over or recombination is equivalent to 1 map unit .

map units apart

In one of Mendel's experiments he crossed two rule breeding pea plants. One produces yellow and round seeds and the other produces green and wrinkled seeds. Yellow and round are dominant traits whereas green and wrinkled are recessive. We will classify yellow as ''Y'' green as ''y'' round as ''R'' and wrinkled as "r" In part A show F1 generation using punnet square. In part B show a punnet square for F2 generation from dihybrid cross. In part C by...

The B and N genes are 25 map units apart on a chromosome. a) Following a dihybrid testcross, how many offspring of 250 would you expect to display a recombinant phenotype? a) If you performed a dihybrid testcross, with a cis dihybrid, what would be the genotypes of both recombinant offspring phenotypic classes?

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

You are studying two genes in corn that you believe may be linked: seed shape and and kernel color. You cross two true-breeding corn plants (one with red kernels and round seeds to one with yellow kernels and wrinkled seeds) and receive all red- kerneled, round seed offspring. You then perform a test-cross using the F1 offspring and a yellow-kerneled, round seed corn and receive the following result: 610 red kernels, round seeds 90 yellow kernels, round seeds 100 red...
