Mandelian genetics
The term used to describe RR and rr is___
The term used to describe Rr is___
1)Homozygous
2)Heterozygous
Describe a term that defines the state of the chromosomes in Prophase?
Homologous Chromosomes
During this phase The cell is not growing and it's undergoing normal cell activity?
G0 Phase
This process copies genetic information from DNA into RNA
Transcription
Is the trait dominant or Recessive?
Recessive
A Rr pea crossed with Rr pea what is the genotypes of the offspring and their ratios?
Rr= 50%
rr= 25%
RR=25%
What happens in metaphase?
Chromosomes line up in the middle of the cell
Proteins at the membrane are pulling the chromosomes apart using the spindle fibres
Independent assortment happens during this phase.....
meiosis I and cross over
This process uses RNA to build a protein
Translation
What is the genotype of #9?
homozygous or heterozygous?
lower case letters (ex: rr)
Homozygous
RR pea is crossed with rr pea, What is the genotype of the F2 generation if offspring is crossed with rr and their ratio?
Rr=50%
rr=50%
The chromosomes are pulled apart and the fibres start to degrade
Anaphase
During tis phase:
Centriole replication and preparation to split
Cell doubled in size by the end
G2 Phase
This theory proposed that organisms develop gradually from undifferentiated material
epigenesis
What is the genotype of parents #3 and 4?
heterozygous or homozygous?
Rr and Rr
heterozygous
A male fly was crossed with a female fly with an rr genotype. F1 generation had genotypes of 50% Rr and 50% rr. what is the genotype of the male fly? Also Identify the Dominant letter.....
Rr / R
The fibers are gone and the homologous chromosomes are on opposite sides of the cell
The cellular membrane starts to pull apart and split into 2 cells
Telophase
Name all phases of Mitosis
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
These are three-base sequences in RNA that specify amino acids.
Codons
What is the genotype for parents#1 and 2?
Heterozygous or homozygous?
2: Rr= heterozygous
If an Rr is crossed with Rr pea what is the probability that F2 generation would have rr genotype if all offsprings are crossed with a Rr pea?
25% or 4/16
A Complete membrane and cytoplasm division is called?
Cytokinesis
Chromosomes replicated once
and divided twice During this process?
Meiosis
This concept explains how genotype leads to phenotype
central dogma of genetics
What is probability of the genotypes between #10, 11, and 12?
RR: 1/3 = 33.3%
Rr: 2/3 = 66.7%
