Genetics 1
The unit that determines traits
What is a gene?
The man whom history credits as the founder of heredity, or, genetics
Who is Gregor Mendel?
An organism's complete genetic makeup.
What is a genotype?
The physical appearance of an organism
What is a phenotype?
Brown eyes, tall, blonde hair are all the ____ of the organism
What is trait?
What we call new (baby) organisms
What are offspring?
The stronger of the two kinds of alleles
What is a dominant allele?
Heredity works by a combination of chance, or what we also call...
Probability
The weaker of the two kinds of alleles
What is a recessive allele?
Passing of genes from one generation to the next is called?
Heredity
This is a heterozygous genotype: AA Tt gg
What is big T; little t? Tt
Mitosis is to this type of reproduction, as Meiosis is to this type of reproduction
What is a Asexual-Mitosis; Sexual-Meiosis
The information needed to fill in a Punnett square
What are the parents genotype?
The classification of this genotype: pp
What is homozygous recessive
The probability of a heterozygous offspring when two heterozygous parents procreat.
What is 50%?
The two types of alleles possible
What is dominant and recessive?
In Mendel's pea plants, the first-generation hybrids expressed the dominant trait how often?
100% of the time
The genotypes of the parents if all the offspring are tt
What is tt? (homozygous recessive)
In this type of reproduction the offspring reproduce rapidly and uniformly
What is Asexual Reproduction
Cross a heterozygous genotype with another homozygous recessive. The probability of the Homozygous dominant genotype appearing would be this
0%
This type of reproduction: requires 2 two parents and the offspring are slightly different from the parent(s)
What is Sexual Reproduction
Crossing a homozygous dominant genotype with a homozygous recessive genotype never results in this genotype
What is homozygous phenotype?
Gray eyes are a recessive trait. Cross a homozygous recessive mother and a heterozygous father. The odds of the child having gray eyes is
What is 50%?
Cross a heterozygous genotype with another heterozygous genotype. The probability of the recessive trait appearing would be this
What is 25%?
