You have a garden of rare Indian Snow Lotus plants. You know that flower color is determined by two alleles of a single gene in this species, a “pink” allele, and a “yellow” allele. One these alleles is completely dominant over the other, but you forgot which one. You decide to cross two plants with yellow flowers to find out. You raise 6 offspring, and all of them have yellow flowers. Based on the results of this cross, which of the following statements do you know is TRUE?

A. The yellow allele is dominant

B. The pink allele is dominant

C. At least one of the parental plants is homozygous at the flower color gene

D. One of the parental plants has the recessive allele of the flower color gene

E. Not enough information to determine which is TRUE

You perform a dihybrid cross of plants. The first trait is flower color. “A” is the dominant allele and causes red petals and “a” is the recessive allele and causes white petals. Stem length is the second trait. “L” is the dominant allele and causes a long stem and “l” is the recessive allele and causes short stems. You cross a Red Long plant that is heterozygous for both traits with a Red Short plant that is heterozygous for color....

In Mendel's pea plants, the genes that code for flower color, seed color and seed shape are on 3 different chromosomes. For flower color, purple is dominant over white, yellow seeds are dominant over green and round seeds are dominant over wrinkled seeds. If you crossed two parents who were heterozygous for all 3 genes, how many purple flowered, round and yellow seeded plants would you expect in the offspring generation? correct answer is 27/64 please show work thank you

Flower color in pea plants exhibits complete dominance as the purple allele is completely dominant over the white alleles. A) Out of 276 pea plants, 273 have purple flowers. Assuming the population is in Hardy-Weinberg Equilibrium, calculate the Expected allele frequencies. B) A group of students counts 552 pea plants. Based on the expected allele frequencies, how many should have purple flowers and how many should have white flowers?

In four-o-clock plants, red flower color (FR) is incompletely dominant over white flowers (FW) and the heterozygous individuals have pink flowers. a. If a red-flowered plant is crossed with a white-flowered plant, what would be the genotypic and phenotypic frequencies of the F1? b. If two of the F1 individuals were crossed, what phenotypes and in what frequencies would appear in the F2?

You are studying three linked genes in snapdragons. The flower color locus is in the center. There are 11.3 cM between the flower color locus and the plant height locus. There are 10.7 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are...

You have been cultivating snapdragons in your garden and allowing plants to re-germinate each year from seeds dropped by the previous year’s annual plants. You know that white flowers are recessive and count 9 white flower plants out of 100 that you examine. Do you find evidence for evolution acting in your population? If yes, could natural selection be involved? Can we calculate using HWE here or we can't because if we calculate q^2 then we are assuming the population...
