Question

Which of the following statements describes mono hybrid cross?
A) Cross between two plants differing in one character of the same species. B) Cross where only one parent plant is used C) Cross between two plants differing in two characters D) Cross between two species of plants of the different species.

Answer 1

Answer:

Concept :

A monohybrid cross is made up of two organisms that have distinct variants at the same genetic locus. In a monohybrid cross, two or more variants for a single gene site control the trait under study. Each parent is selected to be homozygous or true breeding for a certain characteristic in order to perform such a cross (locus). When a cross meets the requirements to be classified as a monohybrid cross, it is typically identified by a distinctive distribution of second-generation (F2) offspring, also known as the monohybrid ratio.

Explanation:

• In a monohybrid cross, two or more variants at a single gene locus control the character under study. Each parent is chosen to have homozygosity, or genuine breeding, for the desired trait, in order to carry out such a cross (locus).
• A distinctive distribution of second-generation (F2) offspring, commonly referred to as the monohybrid ratio, is typically used to identify a cross as meeting the requirements for a monohybrid cross.

• When two organisms with distinct variants on the same genetically significant chromosome are mated, this results in a monohybrid cross.
• Having two dominant alleles in one parent and two recessive alleles in the other.
• One dominant and one recessive allele for that gene are present in each and every offspring. In order to create F1 plants, a monohybrid cross, Mendel crossed two plants that differed in one feature.
• The answer is A cross between two plants of the same species differing in one character is called a monohybrid cross.

Answer 2

Answer:

Option A is correct. Cross between two plants differing in one character of the same species.

Explanation:

• A monohybrid cross is made up of two organisms that have distinct variants at the same genetic locus.
• In a monohybrid cross, two or more variants for a single gene site control the trait under study. Each parent is selected to be homozygous or true breeding for a certain characteristic in order to perform such a cross (locus).
• When a cross meets the requirements to be classified as a monohybrid cross, it is typically identified by a distinctive distribution of second-generation (F2) offspring, also known as the monohybrid ratio.
• A monohybrid cross is a genetic mix between two individuals who have homozygous genotype or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait.

Therefore option A is correct. Cross between two plants differing in one character of the same species.
