Inheritance of Two genes

A homozygous tall pea plant with yellow seeds is crossed with a dwarf pea plant with green seeds. The phenotypic ratio of its F₂ plants would be:

If tall (T) is dominant over dwarf (t) and round seeds (R) is dominant over wrinkled seeds (r). If the genotype is ttRr the phenotype would be

Morgan gave linkage in which year?

"Some phenotypes may have multiple genotypes and some other phenotypes may have a single genotype" -- justify the statement from the results derived from the dihybrid experiment in case of pea plant.

Morgan observed tight linkage in Drosophila with only 1.3 percent recombination for:

The percentage of double dominant phenotypic progeny formed in F₂ generation of Mendel's dihybrid cross is:

How many Pea plants will be dwarf in a mendelian dihybrid cross for height and flower color in F₂ generation ?

Select the odd one out with respect to chromosomal theory of inheritance :

All of the given are reasons why Drosophila was used as experimental material by Morgan, except

What is hybridization?

Choose correct statements from the following:

A) The frequency of recombination between gene pairs on different chromosomes is the measure of distance between those genes.

B) Drosophila completes its life cycle in about two weeks.

C) deVries, Correns, and Morgan rediscovered Mendel's results.

D) Due to the visualization with staining, the term chromosome was coined.

In F₂ generation of a dihybrid cross, Tall red and Tall white flowers obtained in the ratio of 1:1. What is the genotype of the parent plant?

The number of offspring produced in F₂ generation of dihybrid cross is 1600. Find the number of F₂ offsprings with double dominant phenotype?

Can you, using the Punnett square data work out the genotypic ratio at the F2 stage and fill in the format given? Is the genotypic ratio also 9:3:3:1?

Genotypes found in F2 _________ and Their expected Phenotypes​ _______________.

In 'Mendel' dihybrid cross, which of the following result was obtained in ${\mathrm{F}}_2$ generation?

A plant with a full green pod is said to be homozygous dominant. A plant with constricted yellow pod is said to be homozygous recessive. Crossing of these two plants can give rise to plants with full yellow pods. Plants with constricted green pods are also observed. Workout a cross for such type and explain its phenotypic ratio.

The genotype found in F₂ is 1 : 2 : 2 : 4 : 1 : 2 : 1 : 2 : 1. What is the expected phenotype?

Cytological observation made in a many number of ______ led to the development of the concept of genetic/chromosomal basis of sex determination
