- Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?Use the figure and the following description to answer the question(s) below. In a particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true- breeding, dark- leaved plant is crossed with a light- leaved one, and the F1 offspring is allowed to self- pollinate. The predicted outcome of the F2 is diagrammed in the Punnett square shown in the figure, where 1,2,3, and 4 represent the genotypes corresponding to each box within the square. D d D 1 2 4 Which of the boxes marked 1- 4 correspond to plants with a heterozygous genotype? 2 and 3 1 1,2, and 3 2, 3, and 4 3.Give typed explanation : In peas, tall (T) is dominant to short (t). A homozygous tall plant is crossed 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?
- In Japanese four o'clock plants red (R) color is incompletely dominant over white (r) flowers, and the heterogynous condition (Rr) results in plants with pink flowers. Construct a punnett square and give phenotypic and genotype ratios of the offspring for the following cross a red plant and a white plantWaxy endosperm (wx), shrunken endosperm (sh) and yellow seedling (v) are encoded by three recessive genes in corn that are linked on chromosome 5. A corn plant homozygous for all three recessive alleles is crossed with a plant homozygous for all the dominant alleles. The resulting F1 are then crossed with a plant homozygous for the recessive alleles in a three point test cross. The progeny of the test cross are: wx sh WX SH V WX SH V Wx sh WX sh V SH v SH V V 87 1,515 94 WX 1,531 3,479 292 WX Wx sh v 3,478 280 a. Determine the order of the genes on the chromosome. b. Calculate the map distances between the genes. c. Determine the cc and I.D D 1 2 d In a particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true-breeding, dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of the F2 is diagrammed in the Punnett square shown in the figure, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square.

- Tallness (T) in a certain plant is dominant to short (t), while red (R) flower color is dominant to yellow (r). The heterozygous condition results in orange (Rr) flower color. A short plant with red flowers, is crossed with a plant homozygous for tallness and yellow flowers. What would be the genotype and phenotype of the F1 individuals? ttRr—short and orange ttrr—short and yellow TtRr—tall and red Ttrr—tall and yellow TtRr—tall and orangeThe diagram shows a plant that is heterozygous for two genes. G = yellow; g = green; R = round; r = wrinkled G Four different types of gametes are produced by a heterozygous individual when crossing over occurs, and two different types of gametes are produced when crossing over does not occur. What does this information reveal about crossng over? O Crossing over introduces variety by producing different combinations of alleles. O Crossing over reduces the incidence of DNA and chromosomal mutations. O Crossing over introduces variety in by creating types of genes. O Crossing over maintains the count of genes and the original alleles in both chromosomes.

Dominant and recessive alleles, F and f, of another gene cause seeds to be spotted or not with violet color, respectively. A plant of genotype GGFF is crossed with a plant of genotype ggff, and the F1 are allowed to self-fertilize. The phenotypes and numbers of F2 progeny are shown below: Phenotype of F2 Number yellow, spotted 89 green, spotted 31 yellow, not spotted 29 green, not spotted 11 Are the G,g and F,f genes linked?
