In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r):
Mention the Phenotype and Genotype ratios of the offspring in `F_2` generation.

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): Briefly explain the term 'Mutation'.

Give the Phenotypic and Genotypic ratio of the F_1 " and " F_2 generation.

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): What is the number of chromosomes in the gametes of human beings?

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): Name the sex chromosomes in human males and females.

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): Draw a Punnett square to show the gametes and offspring when both the plants have heterozygous round seeds (Rr).

In a homozygous pea plant, axial flowers (A) are dominant over terminal flowers (a). What is the phenotype and genotype of the F_1 generation if a plant bearing pure axial flowers is crossed with a plant bearing pure terminal flowers?

In a homozygous pea plant, axial flowers (A) are dominant over terminal flowers (a). What is the phenotypic ratio and genotypic ratio of the above cross shown in (ii)?

A homozygous plant having round (R) and yellow (Y) seed is crossed with a homozygous plant having wrinkled (r) and green (y) seeds. Give the dihybrid phenotypic ratio and the phenotype of the offspring of the F_2 generation when two plants of the F_1 generation are crossed.

F_(2) generation has genotypic and phenotypic ratio of 1:2:1. It is

(a) Dihybrid cross between two garden pea plant one homozygous tall with round seeds and the other with wrinkled seeds was carried. (i) Write the genotype and phenotype of the F_(1) progeny obtained from this cross. (ii) Give the different types of gametes of the F_(1) progeny. (iii) Write the phenotypes and its ratios of the F_(2) generation obtained in this cross along with the explanation provided by Mendel. (b) How were the observations of F_(2) progeny of dihybrid crosses in Philosophical by Morgan different from that of Mendel carried in Pea plants ? Explain giving reasons.
