Unit 7 Biology: Gregor Mendel's Work and Principles of Genetics

Genetics

Branch of biology studying how genetic information is transmitted from parents to offspring.

Fertilization

The process where male and female gametes (sex cells) fuse, combining their chromosomes and genetic material to create a new individual

Trait

A specific feature or characteristic of an organism

Hybrid

Two different alleles for a gene (e.g., Bb).

Gene

enes are segments of DNA that provide instructions for building specific proteins or traits. They are the fundamental units of inheritance.

Allele

when they go

Principle of Dominance

Survival of the fittest

Segregation

seperation

Gamete

the reproductive

F2 generation

The name of the 2nd generation was th F2 generation

Color of flowers in F1 generation

The color of the flowers where purple

Unexpected aspect of F2 generation

The reapearence of the white flowers where unexpected

Ratio of purple to white flowers in F2 generation

The ratio of purple to white 3:1

Mendel's Law of Segregation

Each individual has two alleles for each trait and these separate alleles during the gamete transformatio and they each recibe one alle

Mendel's 2nd law of inheritance

Alles for different traits are inherited independently of each other

Red hair and freckles

Bcouse of a disfunciion in the M1cr gene

RR genotype

The RR us homoozygous

Rr genotype

heterozygous

Phenotype of Yy

yellow

Probability of Rr X Rr producing wrinkled seeds

1/4

Huntington's Disease

dominant

Genotype hh for Huntington's disease

homozygous recessive

Desire to know about human probabilities

I would want to know more abt human probablillities
