In a particular plant, a recessive allele is associated with white flowers (w). The dominant allele (W) results in purple flowers. Two plants are crossed. The offspring are made up of 175 plants with purple flowers and 161 plants with white flowers. Using the allele symbols shown above, the genotypes of the two parents are Ww x ww. This mating is an example of a/an ?

Answer #1

Answer :

The cross between Plant having purple flower with genotype Ww with a plant having white flower with genotype ww resulted in 175 plants with purple flowers and 161 plants with white flowers. It can be said that the ratio of the Offsprings is almost 1 : 1. Therefore this is an example of a monohybrid test cross.

A test cross is a cross between the offspring heterozygous genotype with the homozygous recessive parent which helps in confirming the pure breeding of the homozygous dominant parent. The cross is as given below :

Purple flowers (P) are completely dominant over white flowers (p) in pea plants. A plant that is heterozygous for purple flowers (male) is crossed with another plant that has white flowers (female). Use a Punnett square to determine the expected genotypic and phenotypic ratios for the offspring. What is the purple pea plant's genotype? What is the white pea plant's genotype? What are the purple pea plant's gametes? What are the white pea plant's gametes? What is the expected genotypic...

A species of plant is discovered in which individual plants produce either white or purple flowers. True breeding plants that have short stems with white flowers are crossed with true breeding plants that have tall stems and purple flowers. The resulting offspring all have tall stems with purple flowers. When one of these tall, purple-flowered offspring is crossed with a short, white-flowered plant, plants with the following characteristics were obtained in equal proportions. White flowers on tall stems Purple flowers...

In monkeyflower, an allele for yellow flowers (Y) is dominant over an allele for white flowers (y). At an independently assorting locus, an allele for entire petals (E) is dominant over an allele for fringed petals (e). A plant that is homozygous for yellow and entire petals is crossed with a plant that is white and fringed. A resulting F1 plant is then crossed with a plant that is white and fringed, and the following progeny are produced: 20 yellow...

1) One parent has yellow flowers, which is the dominant allele Y. The second parent has white flowers, the recessive allele y. If the offspring are all yellow, what is the genotype of each parent? 2) A plant is homozygous for the recessive gene "a" causing the plant to be short. What is the genotype and the phenotype of this plant? (In your answer, be very clear about which is the genotype and which is the phenotype). 3) The allele...
