Father of Modern Genetics?

Johann Gregor Mendel

What year was Johann Gregor Mendel born?

1822

Where did Gregor Mendel grew up in?

A farm in Austria

Gregor Mendel was ordained as what? (in 1847)

Augustinian Priest

What university did Gregor Mendel attend?

University of Vienna

Gregor Mendel started studying what? (In 1856)

Pea Plants or Pisum sativum

What did Gregor Mendel publish in 1866?

“Experiments on Plant Hybridization”

What were the reasons why Gregor Mendel’s works were not initially recognized by the scientific community?

When 2 different classes are experimented with each other what is it called?

Hybridization

What is the offspring referred in Hybridization

Hybrid

Why did Mendel choose the Pea Plants?

What are the 3 important parts of the Pea Flower?

Anther (Pollen is formed, contains Male Gametes)

Ovules (Contains Egg Cells, Female Gametes)

Stigma (Stimulates the growth of a Pollen Tube)

The fusion of 1 sperm and the egg results into?

A Zygote

True or False?

The 2nd sperm fuses with the Eccentric Cell to form the Endosperm?

False. (It fuses with the Central Cell)

Provides nutrition for the zygote

Endosperm

Variety that produces the same trait after several generations of fertilization

"Breeding True"

In Mendel’s experiment on Pea Plants what were the Characters/ Characteristics involved?

Height, Flower Color, Flower Position, Seed Color, Seed Shape, Pod Color, Pod Shape

What were the Variants of Each Characteristic?

Height -

Flower Color -

Flower Position -

Seed Color -

Seed Shape -

Pod Color -

Pod Shape -

Height - Tall, Dwarf

Flower Color - Purple, White

Flower Position - Axial, Terminal

Seed Color - Yellow, Green

Seed Shape - Round, Wrinkled

Pod Color - Green, Yellow

Pod Shape - Smooth, Constricted

This means that an experimenter observes a Single Character.

Monohybrid/ Single-factor Cross

A generation in which both parents are Homozygous for different traits.

P Generation (Parental Generation) or (P Cross)

This generation is the result of the P Cross?

First Filial Generation (F1 Generation)

True or False?

The F1 Generation contains both Heterozygous Parents.

True.

Is able to silence or retest the recessive allele.

Dominant Allele

Starting what generation can recessive traits be observed

Second Filial Generation (F2 Generation)

Genetic Determinant of Traits are passed along as?

Unit Factors

What are the 3 Main Observations that Mendel found throughout the Monohybrid Crosses?

True or False?

The F1 Generation only shows Dominant Phenotypes.

True.
