Concept explainers
a.
To determine:
The number of chromosomes in the plant with AABBC chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
The condition that describes the cells containing only complete sets of chromosomes is referred to as euploid.
b.
To determine:
The number of chromosomes in the plant with BBBB chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
Chromosome refers to a threadlike structure of DNA (deoxyribonucleic acid) found in the nucleus of the most living cells.
c.
To determine:
The number of chromosomes in the plant with CCC chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
Chromosomes are the protein complexes or DNA that carry the genetic information from one generation to next in the form of genes.
d.
To determine:
The number of chromosomes in the plant with BBCC chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
The complete set of chromosomes in the living cell are referred to as ploidy. The changes in the chromosome can be of two kinds: euploidy and aneuploidy.
e.
To determine:
The number of chromosomes in the plant with ABC chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
A specific portion of DNA that serves as a unit of function by encoding a particular protein is known as a gene.
f.
To determine:
The number of chromosomes in the plant with AABBCC chromosome complement, the term that describes the plant’s genetic makeup, and whether the plant is fertile or sterile.
Introduction:
The plants that are able to produce seeds are known as fertile plants. The incapability of producing offspring is known as sterility.
