Answer:
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Explanation:
Given
Trait 1 - Recessive allele for green color stem is represented by a
and dominant allele for purple color stem is represented by A
Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"
F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)
The following offspring will be produced
AM AM AM AM
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Answer: nitrates
Explanation:
Nitrogen fixation involves the conversion of atmospheric nitrogen into ammonia and organic derivatives, by natural means, especially such conversion, by microorganisms (nitrogen fixing bacteria) in the soil, into a form that can be assimilated by plants.
The easily accessible form by which nitrogen can be obtained by plants is nitrates, as they are very soluble in soil water and easily picked by plant root vessels
