The term used to describe RR and rr is___

The term used to describe Rr is___

1)Homozygous 

2)Heterozygous 

200

A Rr pea crossed with Rr pea what is the genotypes of the offspring and their ratios? 

Rr= 50%

rr= 25%

RR=25%

300

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%

400

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

500

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

Mitosis Steps

100

Describe a term that defines the state of the chromosomes in Prophase?

Homologous Chromosomes 

200

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

300

The chromosomes are pulled apart and the fibres start to degrade

Anaphase 

400

• 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 

500

A Complete membrane and cytoplasm division is called?

Cytokinesis 

Mitosis/ Meiosis / Cell Cycle

100

During this phase The cell is not growing and it's undergoing normal cell activity?

G0 Phase 

200

Independent assortment happens during this phase.....

meiosis I and cross over

300

• During tis phase:

• Centriole replication and preparation to split

• Cell doubled in size by the end

G2 Phase

400

Name all phases of Mitosis

• Prophase

• Prometaphase

• Metaphase

• Anaphase

• Telophase

500

Chromosomes replicated once
and divided twice During this process?

Meiosis 

Central Dogma and DNA

100

This process copies genetic information from DNA into RNA

Transcription

200

This process uses RNA to build a protein

Translation

300

This theory proposed that organisms develop gradually from undifferentiated material

epigenesis

400

These are three-base sequences in RNA that specify amino acids.

Codons

500

This concept explains how genotype leads to phenotype

central dogma of genetics

Pedigree Question

100

Is the trait dominant or Recessive?

Recessive

200

What is the genotype of #9? 

homozygous or heterozygous?

lower case letters (ex: rr)

Homozygous

300

What is the genotype of parents #3 and 4?

heterozygous or homozygous?

Rr and Rr 

heterozygous 

400

What is the genotype for parents#1 and 2?

Heterozygous or homozygous?

1: rr = homozygous

2: Rr= heterozygous

500

What is probability of the genotypes between #10, 11, and 12?

RR: 1/3 = 33.3%

Rr: 2/3 = 66.7%
