You do an experiment with the genetics of plant flower color. You cross a red flowered plant with a yellow flowered plant. The F1 progeny from the hundreds of seeds produced include plants that had red flowers and others with yellow flowers but there are also many plants whose flowers were a wide variety of shades of orange in-between the two extremes (that is not just one color halfway between the parents). What kind of non-Mendelian inheritance can lead to this type of result? Explain.

In rose bushes, red flowers are dominant to white flowers. A purebred (homozygous) red rose is crossed with a white rose. Two roses from this parental cross (two of the F1 offspring) are then crossed. What will be the most common genotype of the next generation (F2) ? Heterozygous White roses Homozygous recessive Red roses Homozygous dominant

Outline the basic hybridization research done by Mendel when crossing a true breading violet flowered plant with a true breeding white flowered plant? In your answer you should indicate the parental generation, the F1, and the F2 results.
This exercise is designed to give you some practice with Punnett squares and Mendel's principals of inheritance. Melanin is a chemical pigment produced in our body that contributes greatly to our skin, eye, and hair pigmentation -it also relates to color of fur, feathers, and such in animals. In general, the more melanin that is produced, the darker the color. A few genes contribute to the type and amount of melanin that is produced. Most people produce melanin in their skin, because it helps protect against the damages caused by the sun. This is why people tan. There is, however, a particular set of recessive alleles that cause a person to produce little or no melanin, and we refer to this as albinism. An animal or person who has little or no melanin is referred to as albino, and this can manifest in hair, skin, and eyes. For humans, this can be a rather dangerous condition as albinos are far more susceptible to sun damage, particularly cancer. In this exercise, the alleles are as…

Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2? 1:2:1 tall:intermediate:short 3:1 tall:short 1:1 tall:short 3:1 short:tall 1:2:1 intermediate:tall:short
Mendel obtained his initial pea plant varieties from local breeders who were developing new varieties that might be useful or interesting. To generate these new varieties, breeders formed hybrids between existing varieties of different phenotypic characteristics by cross pollination, using techniques they doubtless taught to Mendel. After producing a hybrid, they allowed several generations of self-pollination, as happens naturally if the flowers are not disturbed. a. What if a breeder were working with 7 different, independently segregating genes, as Mendel did? How many generations would it take him to have pure-breeding varieties, starting from an F1 hybrid that is heterozygous for all 7 genes? i. What is the probability that an individual in the F2 generation would be pure-breeding (i.e. is homozygous at all 7 loci)? [Hint: this is an “and” calculation since it must be homozygous at each of the 7 loci. ii. What is the probability that an individual in the F3 generation would…
Pigeons display a high color variety, here we try to understand the genetic basis of mixed red & black stippling of the feathers (kitey) and their genetic relation to black and red feather color. We conducted the following crosses: Cross Offspring kitey x kitey 16 kitey 5 black 3 red kitey x black 6 kitey 7 black red x kitey 18 red 9 kitey 6 black Have a look at the cross results and develop a hypothesis to explain the inheritance of kitey, black and red feather color in pigeons (Hint: assume that 2 loci are involved and some type of epistasis occurs) QUESTION: 1. provide hypothesis 2. provide the hypothetical genotypes for each crossing
