What type of plant will produce offspring with all the same traits as the parent?
Mendel's Crosses
The result is highly inbred, or “true-breeding,” pea plants. These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding.
What would produce offspring that were identical to their parents?
Asexual reproduction produces offspring that are genetically identical to the parent, whereas sexual reproduction produces a similar, but genetically unique offspring.
Do all offspring plants have the same traits?
Like most organisms that reproduce through sex, plants have paired chromosomes, with each parent contributing one chromosome to each pair. ... When such plants are bred, they will pass the trait, such as pest resistance, fruit flavor or drought tolerance, to all of their offspring.
Which are different forms of the same gene?
Different versions of the same gene are called alleles. Genes can have two or more possible alleles.
Why was pea plant used by Mendel?
To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). For example, pea plants are either tall or short, which is an easy trait to observe. ... Mendel also used pea plants because they can either self-pollinate or be cross-pollinated.
Are offspring identical to their parents?
In asexual reproduction, offspring are genetically identical to their parents; in sexual reproduction offspring have a mix of traits from their parents. A vast majority of plants and animals reproduce sexually.
What is a genetically identical individual made by asexual reproduction known as?
Organisms produced by asexual reproduction are genetically identical to each other and their parent. They are clones.
Which genotype consists of two identical genes for a given character?
Homozygous also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual may be homozygous dominant (AA) or homozygous recessive (aa). Individuals who are homozygous for a trait are referred to as homozygotes.
What is an example of a trait that is inherited?
Inherited traits include things such as hair color, eye color, muscle structure, bone structure, and even features like the shape of a nose. Inheritable traits are traits that get passed down from generation to the next generation. This might include things like passing red hair down in a family.
Can a plant have offspring?
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent.
What is a trait in genetics?
A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.
What are alternative forms of the same genes called?
"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. Typically, we call them either normal or wild-type alleles, or abnormal, or mutant alleles.
How all humans have the same genes but vary genetically?
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases.
What did Mendel produce when he crossbreed different true breeding plants?
Crosses between true-breeding plants with white flowers produced true-breeding plants with only white flowers. However, when Mendel crossed true-breeding plants with purple flowers and true-breeding plants with white flowers, all of the offspring had purple flowers. Second-Generation Crosses are called Hybrid crosses.
Who is known as the father of genetics?
Like many great artists, the work of Gregor Mendel was not appreciated until after his death. He is now called the "Father of Genetics," but he was remembered as a gentle man who loved flowers and kept extensive records of weather and stars when he died.
