What are the 7 characteristics that Mendel investigated in pea plants?
Mendel used seven pea plant traits in his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
When Mendel cross pollinated purple and white flowered parent plants What did he observe?
the law of segregation and the law of independent assortment. When Mendel cross-pollinated purple- and white-flowered parent plants, what did he observe? The F2 generation was 75% purple-flowered plants and 25% white-flowered plants. that some of the F2 had green, round pods and some had yellow, wrinkled pods.
Would all of the purple-flowered offspring also have short stems Why or why not?
No, all of the purple-flowered offspring would not have short stems. From Mendel’s second set of experiments, the independent assortment of factors would result in purple-flowered offspring having either short stems or long stems.
What is the blending theory of inheritance quizlet?
Blending Theory. an obsolete theory of heredity proposing that the traits of offspring are the average of the parental traits. G. Mendel.
What 3 conclusions were made after Mendel’s experiment?
—and, after analyzing his results, reached two of his most important conclusions: the Law of Segregation, which established that there are dominant and recessive traits passed on randomly from parents to offspring (and provided an alternative to blending inheritance, the dominant theory of the time), and the Law of …
How did Mendel cross pollinate flowers?
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. Then he pollinated them by hand with pollen from other parent plants of his choice. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination.
What are the 3 non-Mendelian inheritance?
Such modes of inheritance are called non-Mendelian inheritance, and they include inheritance of multiple allele traits, traits with codominance or incomplete dominance, and polygenic traits, among others, all of which are described below.
What are the five patterns of inheritance?
There are five basic modes of inheritance for single-gene diseases: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, and mitochondrial.
What are the three main types of inheritance?
The types are: 1. Autosomal Dominant Inheritance 2. Autosomal Recessive Inheritance 3. Polygenic Disorders and Multifactorial Inheritance.
What is pattern of inheritance?
Patterns of Inheritance. The phenotype of an individual is determined by his or her genotype. The genotype is determined by alleles that are received from the individual’s parents (one from Mom and one from Dad). These alleles control if a trait is “dominant” or “recessive”.
