1)
a)the genetic makeup of a particular character is referred as genotype .
b) the physical characters which can be seen and identified is called as phenotype.
c) Dihybrid cross is a cross between two different genes that differ in two observed traits.
d)the phenotypic ratio of different types of individuals occurring in the F2 generation of the mono hybrid cross is called as mono hybrid ratio.
e) a genetic cross between a homozygous recessive individual and a corresponding heterozygote to determine the genotype of the latter is called as test cross
2)
a) the determining agent of a particular character is called a factor. a factor(also known as gene) is a segment of nucleic acid called DNA present inside a nucleus
b)each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome are called alleles
c) the removal of anthers of a flower in order to prevent self pollination or the undesirable pollination of neighbouring plants is called emasculation
d)An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types.
e) a hybrid that is heterozygous for alleles of two different genes
