When an albino female plant of maizeis crossed with normal green male plant, all plants in the progeny are albino because
Plastids are inherited through maternal plants
Albinism is dominant over green character
The crossing results in structural changes in green plastids
Green plastids of male parents become mutated
Polytene chromosomes in salivary glands of are formed as a result of
A tobacco plant which is heterozygous for albinism $(a\, recessive\,character)$ is self pollinated if $1200$ seeds are subsequently germinated, how many of the seedlings would have the parental genotype
How many conditions exhibit in dissimilar sex chromosomes?
Which of these is a dominant factor?
In a gene pool, along with beneficial mutations those mutations also exists which are damaging to an individual. It has been found that these mutations are irreversible because
$I.$ they have survival value
$II.$ they are acquired
$III.$ they are recessive and carried by heterozygous individuals only
$IV.$ they show genetic drift
