Homework Answers
3) tall plant can be either TT or Tt so to determine the genotype test cross can be done that is cross with recessive individual tt
TT*tt will yield only Tt progenies which are tall.
Tt*tt
| T | t | |
| t | Tt (tall) | tt (Short) |
| t | Tt (tall) | tt (short) |
if the plant is Tt then both tall and short plants are produced in ratio 1:1.
4) Incomplete dominance is when heterozygotes produce the intermediate phenotype of homozygotes
example:
in snapdragon
If you cross a n true breeding red flowered plant (RR) to a true breeding white flowered plant (rr)
progenies are all pink coloured (Rr) and in F2 progenies Red:Pink:white=1:2:1
Rr *Rr
| R | r | |
| R | RR (red) | Rr (pink) |
| r | Rr (pink) | rr (white) |

8. Pea plant breeders wanted to pick healthy tall plants that were homozygous for the height gene. They had a collection of 10 plants that were healthy and tall, but the genotypes were unknown. How might they determine if the 10 tall plants were heterozygous or homozygous for the height gene? a. What genotypes are possible for tall pea plants? b. What cross would be most useful in distinguishing between homozygous and heterozygous tall plants? c. Explain the concept of...

Let's use this equation to solve the following problem: In pea plants, the allele for tall plants (T) is dominant to the allele for dwarf plants (1). If a population of 100 plants has 36 dwarf plants, what is the frequency of each allele? Here is a step-by-step guide: 1. Let p = frequency of the dominant allele (R), and q = frequency of the recessive allele (1). 2.92 = frequency of the homozygous recessive = 36%, or 0.36. Since...

1.
There is a gene for height in a species of pea plant that we will
call "T gene". We would denote the dominant allele for this gene as
_____ and the recessive allele as _____. A homozygous dominant
individual's genotype would be _____, a homozygous recessive
individual's genotype would be _____, and a heterozygous
individual's genotype would be _____.

In pea plants, height is controlled by a single gene and the tall allele (T) is dominant to the short allele (t). You find a tall pea plant in your yard and cross it with a short pea plant. It gives rise to 43 tall offspring and 35 short offspring. What is the genotype of the tall parent plant? Answers: Tt tt TT

a) In radishes, the plants can be tall (allele T) or dwarf (allele t). Tall is dominant. Root color can be red (allele RR), white (allele RW), or pink (heterozygote). A radish that is true-breeding for both red roots and tallness (RRRR TT) is crossed with a radish that is true-breeding for both white roots and being dwarf (RWRW tt). Write the genotype and phenotype for the F1 generation. b) Assume the two genes for plant height and root color are...

If you have an F1 generation that is heterozygous for the tall/dwarf allele, cross them to produce an F2 generation. Draw a Punnett Square for that cross here. a. In the F2 generation, what is the probability that the first 3 pea plants you grow will all be tall? You must show your work. b. In the same F2 population, find the probability that 5 out of 7 plants will be tall. Use the bionomial expansion equation. This procedure is...
