A farmer crossed a tall (T) pea plant carrying yellow seeds and a dwarf pea plant (t) carrying green seeds . Tall is dominant over the dwarf and yellow is dominant over the green. Fertilization of the first generation pea plants produced a total of 16 second filial generation offsprings of the pea plants. How many tall pea plants that will have green seeds can you expect to be produced? What will be the genotype of these plants (Homozygous? Heterozygous? Or Both?).

In peas, tall (T) is dominant to short (t). A homozygous tall plant is cross with a short plant. The F1 are self fertilized to produce the F2. Both tall and short plants appear in the F2. If the tall F2 are self fertilized, what types of offspring and proportions will be produced? (Show all your work) please use the punnet square

What will be the phenotypic ratio of the offspring of a purebreed male fly with eosin eyes (CCXw-eY) mated to a red-eyed female who is heterozygous for both the cream (C) and eosin eyes (Xw-e) allele.

The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…

Purple (P) flower color is dominant to white (p) flower color. Cross two heterozygous parents using a Punnett square. What are the genotypes and phenotypes of the resulting offspring? Express the results as ratios.

What progeny would result from crossing a homozygous rose-combed hen with a homozygous pea-combed rooster? What phenotypes and ratios would be seen in the F2 progeny?

Two true breeding plants are cross pollinated. One plant is homozygous dominant for heightand color while the other is homozygous recessive for height and color. (A:tall, a:short, B:brown,b:red) The F1 plants are allowed to self-fertilize to produce an F2 generation. After conductingan experiment we get the following results:398 tall and brown plants122 tall and red plants128 short and brown plants45 short and red plants Using the Chi Square formula and table, determine if your results support the hypothesis ofindependent assortment or not. Show your work. You don’t need to show your Punnett Squaresif you include a statement as to how you figured out the appropriate phenotypic ratio for the F2generation. Round to 1 decimal.4a. What possible gametes can the following individual make: AaBb4b. What possible gametes can the following individual make: AaBbCC

In certain lizards, scaly skin is dominant to smooth skin and speckled color is dominant to grey color. These traits are inherited according to traditional Mendelian genetics (no linkage). The total progeny for a breeding pair of lizards resulted in the offspring listed below. What are the genotypes of the male and female parents? 102 scaly skinned, speckled off spring 110 smooth skinned, speckled offspring 38 scaly skinned, grey offspring 32 smooth skinned, grey offspring

Suppose a purple flower heterozygous for stem size is crossed with a large stem (dominant) purple flower. What are the possible genotypes and phenotypes of offspring?

Red flowering plant are crossed with white flowering plant. The offspring shows: 1 red: 2 pink: 1 white. What are the genotypes of the parents?
