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
Homework Answers
What is the genotype of the tall parent plant?
Answer- Tt.( tall parent)
The tall plant can be TT or Tt.
The dwarf plant can be tt.
Tt X tt
| T | t | |
| t | Tt | Tt |
| t | Tt | tt |
TT and tt are incorrect.
If TT was a parent and crossed with a dwarf plant then all plants will be tall.
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!

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 tomatoes, there are two alleles for the height gene. The tall allele is dominant over the short allele. You cross a heterozygous plant with a homozygous recessive plant. What phenotypes do you expect in their offspring?

A heterozygous tall plant is crossed with a short plant.
What is the expected phenotypic ratio?
In pea plants, tall (T) is dominant and short (t) is recessive. A heterozygous tall plant is crossed with a short plant. What is the expected phenotypic ratio? all offspring will be tall 3:1 1:2:1 9:3:3:1 1:1 all offspring will be short

2) In pea plants, pod shape is controlled by a single gene with 2 alleles with the dominant allele (F) producing full pods and the recessive producing constricted pods. You cross 2 individuals with full pods and get 150 with full pods and 35 with constricted pods. Test the hypothesis that the parental genotypes were ff and Ff using a chi-square test.

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...

13. The D gene in pea controls plant height. DD and Dd plants are tall and dd plants are short. In a particular population of pea plants, 64% of the individuals are tall, and the population is at Hardy- Weinberg equilibrium. Suppose that a change in climate imposes a selection coefficient (s) of 0.25 on the tall plants. After one generation in this new environment, what is the estimated frequency of the D allele? A. 0.4 B. 0.192 C. 0.378...
