d. 2:2:2
e. None of these -
The green bugs in the above question are ........ a. Homozygous dominant b. Homozygous recessive c. Heterozygous d. It is impossible to tell from the given information e. None of these

A homozygous purple-tall sweet pea is crossed with a homozygous white- short pea. The offspring are all purple-tall. This generation is now crossed. What will the phenotypic ratio be PT:Pt:pT:pt. a. 9:3:3:1b. 8:8:0:0 c. 4:4:4:4 d. 2:6:6:2 e. None of these
- If your ratio was 3:0:0:1, what would you correctly suspect? a. I must have goofed up b. The two traits must be linked c. The two traits must be sex-linked d. The two traits must be located on different chromosomes e none of these

If you correctly expected a 3:0:0:1 ratio, and you obtained a 2.5 : 0.1 : 0.1 : 0.3 ratio, what would you now suspect?
a. I must have really goofed up!!
b. The traits are very tightly linkedc. The traits are linked and some crossing has taken place d. The traits are sex-linked and crossing over has taken place e. None of these

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...

Question 29 0/2 pts Two unlinked, epistatic genes regulate production of flower pigments in diploid sweet peas, as shown in the metabolic pathway below. Each gene codes for the production of an enzyme, and each gene has two possible alleles-dominant and recessive. Plants with at least one dominant R allele will produce the blue pigment. Plants with at least one dominant R allele and at least one...

1. People wit h the sex-linked genetic disease, hemophilia, suffer from excessive bleeding because their blood will not clot. Tom, Mary, and their 4 daughters do not exhibit symptoms of hemophilia. However, their son exhibits symptoms of hemophilia because: A) Tom is heterozygous B) Tom is homozygous C Mary is homozygous D) Mary is heterozygous E All of the above are equally likely What is the risk of having a child affected by disease with an autosomal recessive inheritance both...

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...
