Two purple flowered pea plants that are heterozygous for this gene are crossed. What percentage of the offspring would be likely to have white flowers? Axial flower position is dominant to terminal flower position A true breeding axial flowered plant is crossed with true breeding terminal flowered plant: Wnat proportion of the offspring would be expected t0 have axial flowers? Terminal flowers? A pea plant that is homozygous (genotype YY) for having yellow seeds is crossed with pea plant that is homozygous for having green seeds genotype (yy). Yellow Y is dominant; while green; Y, is recessive: What would be the genotype of the gametes produced by the green seeded pea plant? What would be the genotype of the offspring of the above cross? Yellow seeded YY Green seeded Yy What would be the phenotype of the offspring of the cross in number 3? Tall pea plant height is dominant to short (dwarf) height A heterozygous tall plant is crossed with a dwarf plant What is the probability that the offspring are tall? What is the probability that the offspring are dwarf? You have a tall pea plant, but you do not know if it is heterozygous or homozygous. Describe how you would do a test cross to find out: A single gene controls the presence of horns on Hereford cattle. Homless (H) condition dominant over horned (h) condition_ A hornless cow is crossed repeatedly with the same horned bull. The F, offspring include 8 homless and 7 homed animals What are the genotypes of the parents? How do you know?
