Cytoplasmic male sterility in maize is manifestation of interaction between
Chloroplast and nuclear genes
Mitochondrial and nuclear genes
Chloroplast and mitochondrial genes
Cytoplasmic factors and male sterile genes
One of the parents of a cross has a mutation in its mitochondria. In that cross, that parent is taken as a male. During segregation of ${F_2}$ progenies that mutation is found in
The following diagram shows two chromosomes and the lettered number represents the genes
chromosome $1$ :
$P$ | $Q$ | $R$ | $S$ | $T$ | $U$ | $V$ |
$W$ |
chromosomes $2$ :
$E$ | $F$ | $G$ | $H$ |
Which of the following would result if a translocation occurred between chromosome $1$ and $2 ?$
Which mutation causes change in allele?
Match the columns :
Column $I$ |
Column $II$ |
$(1)$ Lethal mutation | $(a)$ Mutation caused by external factors |
$(2)$ Spontaneous mutation | $(b)$ They are metabolic errors |
$(3)$ Induced mutation | $(c)$ As a result the mutant dies |
$(4)$ Biochemical mutation | $(d)$ Most of the mutations occurs in nature are of this type. |
