Mitosis was first described closest to? 1600, 1700, 1800, or 1900.
1900
The product of mitosis in one diploid nucleus will be?
Two diploid nuclei, genetically identical
What is the product at the end of meiosis?
Four haploid nuclei, genetically different
The evidence of heritable abnormality, say hemophilia or red/green color blindness which is more frequent in males than females is a strong indication that the gene controlling the malfunction is on which chromosome?
On the X chromosome
How many bivalents are present at the end of prophase 1 of meiosis in a diploid nucleus?
The haploid number
Repeated inbreeding in a population results in increased levels of disability because of?
An increasing homozygosity.
Name the person.
Biological Classification
Linnaeus
Name the person.
Discovering bacteria/microorganisms
Pasteur
Name the person.
Genetics
Mendel
Name the person.
Cell Nucleus
Brown
Name the person.
Population growth
Malthus
Which is more reliable? Hypothesis or theory?
A theory
Biology is the study of?
Living things
Evolution has occurred by the process of?
Natural selection
True or False.
The Hardy/Weinberg Principle proves mathmatically that evolution cannot occur.
False- the conditions for their predictions to be accurate require unnatural conditions in the breeding population.
The genotype of an organism describes?
The collection of genes that the organism has
The phenotype of an organism describes?
What the organism will look like
An individual in which both alleles of a gene are the same is said to be?
Dominant for that gene
What are gametes?
They are haploid
In a classic Mendelian monohybrid cross the phenotypic ratio in the F2 generation would be?
3:1
What would be the phenotypic ratio for a classic Mendelian dihybrid cross?
9:3:3:1
If in a dihybrid cross following Mendel's example you found only 2 recombiant plant phenotypes in 500 F2 plants, what would you conclude?
The two genes you had chosen to work with were "linked"
In another dihybrid cross experiment in which Mendel's predictions were fulfilled exactly, the genotype of the F1 individuals was XxYy. What are the possible gametic genotypes from those F1's?
XY, Xy, xY, xy
Mendel identified 'dominant' and 'recessive' factors. Today these would be described as?
Alleles of one gene
Name that person.
Inheritance of aquired characteristics
Lamarck
Name that person.
Allele frequency in a population
Hardy and Weinberg
Name that person.
Chemical Evolution
Stanley Miller
Name that person.
The Cell Theory
Schleiden and Schwann
