In pea plants, yellow seeds (Y) are dominant to green seeds (y) and round seeds (R) are dominant to wrinkled seeds (). The genes for seed color and seed shape are on different chromosomes. Two true-breeding parents, one with yellow round peas and the other with green wrinkled peas, are crossed to produce a hybrid (heterozygous) F₁. Two F₁ individuals are crossed to give an F2; this is depicted in the Punnett square below. Place the correct genotypes in the Punnett square and the place the correct phenotypic ratios next to their appropriate phenotype on the right.

In corn, purple kernels (P) are dominant over yellow kernels (p) and starchy kernels (Su) are dominant over sugary kernels (su). A corn plant grown from a purple and starchy kernel is crossed with a plant grown from a yellow and sugary kernel, and the following progeny (kernels) are produced: Phenotype Num purple, starchy 15 purple, sugary 14 yellow, starchy 16 yellow, sugary 11 Formulate a hypothesis about the genotypes of the parents and offspring in this cross. Perform a chi-square goodness-of-fit test comparing the observed progeny with the numbers expected based on your genetic hypothesis. What conclusion can you draw based on the results of your chi-square test? Can you suggest an explanation for the observed results?
Two genes of a flower, one controlling blue (B) versus white(b) petals and the other controlling round (R) versus oval (r)stamens, are linked and are 10 map units apart. You cross ahomozygous blue oval plant with a homozygous white round plant. The resulting F1 progeny are crossed with homozygouswhite oval plants, and 1,000 offspring plants are obtained.How many plants of each of the four phenotypes do youexpect?
In autotetraploid Chinese primrose (Primula sinensis L.), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. Each of the F1 GGgg plants would obtain 12 gametes which are 2GG, 8Gg, and 2g. How were these obtained?
Thorn apples produce either purple (P) or white (p) flowers, and their fruits are either spiny (S) or smooth (s). These two genes are located on non homologous chromosomes. a. What is/are the phenotypes and genotypes of the offspring that result from the cross PPss x PpSs? b. If the cross PpSS x ppSs is made, which of the following is/are not represented in the offspring? PpSS PpSs ppSS ppSs PPSs
Assume that the trihybrid cross AABBrr x aabbRR is made in a plant species. Assume that A and B are dominant alleles, but there is no dominance effect of alleles at the R locus. a) How many different gametes are possible in the F1generation? What are the genotypes of these gametes? b) What is the probability of the parental aabbRR genotype in the F2 progeny? c) What proportion of the F2 progeny would be expected to be homozygous for all three genes?

In Drosophila,, the curled mutation (cu, chromosome 3, position 50.0) results in wings that curl up, while ebony (e, chromosome 3, position 70.7) results in a dark body.

In the following cross, imagine that you have a female fly that has two Xs and one Y due to a nondisjunction event in her mother's germ cells. Draw out what the possible gametes are for both the female and the male and also a Punnett square showing the genotypes, phenotypes, and sex of the possible flies as a result of this cross. You do not need to provide the probabilities of each of these. Red-eyed wi C Ở Red-eyed wt XX Y X Y Meiosis
