Ans. (b) 1:2:1
Being the flowers are heterozygous (Cc) for color and follow the mendelian inheritance,
→ Cc × Cc
C c
C CC Cc
c Cc cc
→ one CC, one cc, and two Cc

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

In carnations, the heterozygous plants have pink flowers, while the two homozygous plants have red flowers or white flowers. When plants with red flowers are crossed with plants with white flowers, what proportion of the offspring will have pink flowers? zero twenty-five % O fifty % O seventy five % one hundred %

II. MONOHYBRID PROBLEMS WITH INCOMPLETE DOMINANCE 8. Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R R are red-flowered, those that are heterozygous (R W ) are pink, while those with the (WW ) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1? __________________________________________________________ b. What...

0. In snapdragons, the alleles for flower color show incomplete dominance. CRCR produces red flowers; CWCW produces white flowers and CRCW produces pink flowers. The height of the plant is determined by a separate gene with regular dominant and recessive alleles. Normal height (D) is dominant over dwarf height (d). a. A snapdragon that is heterozygous normal in height and has white flowers is crossed with a plant that is dwarf in height and has red flowers. What is the...

Answer the following questions for the dihybrid cross described. In a plant blue flowers crossed with white flowers results in blue and white spotted. Additionally, broad leaves are more common even when crossed with thin. (A) What is the mode of inheritance of flower color? Cross: A (1) true breeding blue flower plant with broad leaves is crossed with a (2) blue and white spotted flower with thin leaves. (B) What is the genotype of the two parents involved in...

In sweet peas, two genes (genes A and B) control flower color. The dominant alleles of both genes produce enzymes that function in the biochemical pathway shown to convert colorless precursors to a purple pigment. The recessive alleles do not produce enzyme. Therefore, at least one dominant allele of both gene A and gene B are required for purple flowers. Answer the questions about this biochemical pathway. ΑΑ, Αα BB, Bb Enzyme A Enzyme B Colorless precursor 1 Colorless precursor...

1. In carnations, the heterozygous plants have pink flowers, while the two homozygous plants have red flowers or white flowers. When plants with red flowers are crossed with plants with white flowers, what proportion of the offspring will have pink flowers? - 08% - 25 % - 50 % - 75 % - 100 % 2. Albinism (lack of skin pigmentation) is caused by a recessive mutation on one of the autosomal chromosomes. A man and woman, both with normally...
