Question

define monohybrid cross. how does traits get expressed​

Answer 1

Answer:

The cross begins with the parental generation. One parent is homozygous for one allele, and the other parent is homozygous for the other allele. The offspring make up the first filial (F1) generation. Every member of the F1 generation is heterozygous and the phenotype of the F1 generation expresses the dominant trait.

Answer 2

MONOHYBRID CROSS: A monohybrid cross is a cross conducted to study the inheritance of a single gene.

For Example, a cross between a tall(TT) plant and a short(tt) plant is said to be a monohybrid cross.

There are different types of alleles for a gene and these alleles are responsible for expression of a trait.

A dominant allele is one which can express itself in heterozygous condition too, while a recessive allele can express itself only in homozygous condition.
