This image shows the offspring that result from a dihybrid cross between a plant with wrinkled green seeds and a plant with round yellow seeds. Generation Generation 2 round, yellow wrinkled, yel wrled green How can this graphic be used to support the idea of independent assortment? O The fact that the seeds can be one of two different colors shows that the chromosomes with the seed color gene must sort independently. O The fact that the seeds can be one of two different textures shows that the chrorhosomes with the seed texture gene must sort independently. O The idea that alleles sort independently is supported by the fact that some second generation offspring have trait combinations that the first generation parents do not have. O The idea that alleles sort independently is supported by the fact that some second generation offspring have the same trait combinations that the first generation parents have. https://student.masteryconnect.com/?iv=it4119tzPsQ…
. In nature, the plant Plectritis congesta is dimorphic forfruit shape; that is, individual plants bear either winglessor winged fruits, as shown in the illustration.Wingless fruit Winged fruitPlants were collected from nature before floweringand were crossed or selfed with the following results:Number of progenyPollination Winged WinglessWinged (selfed) 91 1*Winged (selfed) 90 30Wingless (selfed) 4* 80Winged × wingless 161 0Winged × wingless 29 31Winged × wingless 46 0Winged × winged 44 0*Phenotype probably has a nongenetic explanation.Interpret these results, and derive the mode ofinheritance of these fruit-shaped phenotypes.

More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross: P1: AABBCCDDEE aabbccddee F1: AaBbCcDdEe (self-cross to get F2) What is the chance of getting an AaBBccDdee individual in the F2 generation?
More Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?
More Crosses with Pea Plants: The Principle of Independent Assortment Think about this one carefully. Albinism and hair color are governed by different genes. A recessively inherited form of albinism causes affected individuals to lack pigment in their skin, hair, and eyes. In hair color, red hair is inherited as a recessive trait and brown hair is inherited as a dominant trait relative to red hair. An albino woman whose parents both have red hair has two children with a man who is normally pigmented and has brown hair. The brown-haired partner has one parent who has red hair. The first child is normally pigmented and has brown hair. The second child is albino. a. What is the hair color (phenotype) of the albino parent? b. What is the genotype of the albino parent for hair color? c. What is the genotype of the brown-haired parent with respect to hair color? Skin pigmentation? d. What is the genotype of the first child with respect to hair color and skin pigmentation? e. What are the possible genotypes of the second child for hair color? What is the phenotype of the second child for hair color? Can you explain this?

During an investigation, two German shepherds with long hair were each bred with a German shepherd with short hair in a first-generation cross. The offspring from each first-generation cross were then bred to produce a second-generation cross. Which questions could be answered using the results of this investigation? Select the three correct answers. O Is hair length in German shepherds a dominant or recessive trait? O How often does the mutation for long hair randomly occur in German shepherds? How does the protein made by the gene for hair length differ among German shepherds? O Is long hair in German shepherds an inherited trait? O What percentage of offspring in the second generation of German shepherds are homozygous for the recessive hair-length trait?
