- 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?arrow_forwardThe following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?arrow_forwardAssuming that the genes are unlinked, what will be the phenotypes of the offspring from the cross above?arrow_forward
- A neighbour gives a home gardener some seeds that he collected last year from his red carnations. The gardener plants 50 of the seeds and is surprised to find 12 of the plants have white flowers. Assuming that all seeds came from one cross. What is the genotype of the parents?arrow_forwardYou have a pea plant with a yellow pea phenotype but do not know if the genotype is homozygous (YY) or heterozygous (Yy). What type of cross would you do determine the genotype of this plant and what would be the predicted phenotypes of the offspring?arrow_forwardImagine you are Performing a cross involving seed color in garden pea plants. What F1 offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green.arrow_forward
- To build a genetic map, how many types of crosses will be required to perform if you have three genes to map? Explain.arrow_forwardA different walnut rooster was crossed to a rose hen, and all the progeny were walnut.

The F1 progeny obtained had orange flowers. What is the inheritance pattern?arrow_forwardIn a particular plant, green seed color is dominant to yellow seed color.
