To determine if a particular plant is homozygous or heterozygous, you would have to test cross with a to make the check.

Homozygous recessive

Explanation:

Diploid (2n) organisms possess two alleles for a specific gene in which one of the allele can mask the expression of another in that gene. The allele that masks the expression of the other is said to be the dominant allele while the allele that is masked is the recessive allele.

The genotype of an individual is the genetic make-up while the phenotype is the expressed trait. Since, an allele can mask the expression of another, it is therefore impossible to ascertain the genotype of an organism by merely looking at its phenotype. The organism can either be homozygous (TT) or heterozygous (Tt) for that trait

N.B: T represents dominant allele of the gene coding for height, and t represents the recessive allele of the same gene

To determine whether an organism showcasing a dominant trait is homozygous or heterozygous for a specific allele, a TEST CROSS is conducted by crossing that organism with an organism with homozygous recessive trait.

N.B: An organism can only exhibit recessive traits if the alleles are homozygous ( same recessive alleles).

If all the offsprings of the cross showcase dominant traits, it means the parent organism is homozygous dominant but if any of the offsprings exhibit recessive traits, it means the parent organism is heterozygous dominant.

answer: 45

explanationyou have to add as well to be it could be

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
