In a particular plant, having short tendrils (T) is dominant to having long tendrils (t), and having yellow flowers (F) is dominant to having white flowers (f). Suppose two plants, one having alleles TtFf and the other having alleles ttFf are cross-pollinated. What is the probability that the resulting offspring will have long tendrils with yellow flowers?
Homework Answers
answer is 3/8=0.375
TtFf x ttFf 
(TF+Tf+tF+tf)x(tF+tf)
(TtFF+TtFf+TtFf+Ttff+ttFF+ttFf+ttFf+ttff)
here first 3 (TtFF, TtFf, TtFf )will have long tendrils with yellow flowers out of 8 offspring ,
so required probability=3/8
TtFf will give four types of gamet (TF, Tf, tF, tf) ( may be gamets terminology will be wrong)
and ttFf will give two type of gamet (tF and tf)
and resulting cross will give 8 offsprings (TtFF, TtFf, TtFf, Ttff, ttFF, ttFf, ttFf, ttff)

In a flowering plant, red flowers are dominant over white flowers, and short plants are dominant over tall plants. A short plant with red flowers was self-fertilized and the phenotypes for the resulting progeny recorded (see below). Based on the observed numbers, you propose the hypothesis that this dihybrid cross follows a 9:3:3:1 phenotypic ratio, whereby Mendel's laws apply. Based on this hypothesis, you calculated the expected number of progeny for each phenotype (see below). Phenotype Observed Number of Plants...

Let's say you have a pea plant that has the dominant traits for Tall stalks and Yellow seeds (TY). You want to know if this plant is homozygous for these traits, or heterozygous. What would you cross it with, and what is this called? A Monohybrid cross: TY X TY a plant with the same phenotype B. Dihybrid cross: a plant with a different trait (pink flowers and tall stalks) C. Test-cross; a plant homozygous for the recessive alleles: short...

In a plant, the allele that results in violet flowers (V) is dominant to one that results in white flowers (v); at another locus, the allele that makes prickly seed capsules (P) is dominant to one that results in smooth capsules (p). A plant with white flowers and prickly capsules is crossed with one that has violet flowers and smooth capsules. The resulting seeds were planted and yielded 50 plants with white flowers and prickly capsules, 46 plants with white...
