In a field of 10,000 pea plants, a farmer observes that 8,500 exhibit the dominant round (R) seed shape. How many of the the individual plants are likely heterozygous for round seeds? 1,500, 3,700, or 4,800

In a population of plants, leaf hairiness is determined by a single locus with two alleles: H and h. Out of 319 individuals in the population, 25 % are completely hairy, 9 % are partially hairy, and the remaining are hairless. Complete hairiness is caused by homozygosity of the H allele at a single locus; hairlessness is caused by homozygosity of the h allele at that locus; heterozygotes are partially hairy. What is the expected (predicted under H–W) number of individuals with partially hairy leaves?

A researcher at ASU is studying the exotic Unicorn Fairy plant. The plant has three genes of interest with the dominant alleles being T-tall, H=hairy leaves and P=purple flowers. The three genes are located in different chromosomes. A trihybrid plant is crossed with a plant that is heterozygous for T and homozygous recessive for the other two genes. What is the probability of getting offspring that is tall, has hairy leaves and white flowers? 9/64 5/8 8/64 O 3/64 O 3/16

A man with red hair (hh) reproduces with a heterozygotic woman (Hh). Does the woman have red hair?  What about their children?  Create a Punnett square and determine the ratio or percentage of their offspring that have red hair. As stated in the discussion of independent assortment and dihybrids above, pea color and coat texture are independent traits in pea plants. Yellow (G) is dominant over green (g) and smooth (W) is dominant over wrinkled (w). What would the phenotypic ratios of the offspring of parents with genotypes GGww and ggwW? Show your work with a Punnett square. Review the information on Labrador retrievers above.  What are the phenotypic ratios of the F1 generation offspring of two dihybrids? Make sure to match the numbers with coat colors (e.g, which number in the ration goes with which color).  Use a Punnett square to determine the ratios and show your work.  Make sure to state the phenotypic ratios.  Finally, what color are the parents? Two other Labradors mate and…
