An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show' and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism. [ 1 ] [ 2 ] The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological ...
The plant's offspring inherit the new genes, which has led to concern about the spread of new traits into wild plants. [22] The kind of technology used in genetic engineering is also being developed to treat people with genetic disorders in an experimental medical technique called gene therapy. [23]
The plant with the bb genotype will have the recessive trait. These inheritance patterns can also be applied to hereditary diseases or conditions in humans or animals. [11] [12] [13] Some conditions are inherited in an autosomal dominant pattern, meaning individuals with the condition typically have an affected parent as well. A classic ...
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It ranges widely, from the number of species to differences within species, and can be correlated to the span of survival for a species. [1] It is distinguished from genetic variability, which describes the tendency of genetic characteristics to ...
WASHINGTON (AP) — Two-thirds of animal and plant populations are declining in genetic diversity, which makes it harder to adapt to environmental changes, according to research published Wednesday. Long before a species goes extinct, the population becomes smaller and more fragmented , shrinking the number of potential mates and therefore ...
When diseases are caused by environmental influences, such as iodine deficiency or lead poisoning, their resultant symptoms are unequivocally agreed to be acquired characteristics. However, it is debatable whether changes in bodily functions due to disorders that are partly or wholly genetic in origin are actually "acquired".
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
