Genetics
The study of heredity.
What is genetics?
The passage of genetic information from parents to offspring.
What is heredity?
Sexual reproduction produces offspring that are genetically _____________ to the parents.
What is Similar or Diverse?
Some genes can be hidden or covered up by another. These are considered to be-
What is Recessive?
What is environment?
Sections of a chromosome that code for a specific trait.
What are genes?
The father of Genetics.
Who is Gregor Mendel?
Asexual reproduction produces offspring that are genetically ____________ to the parent.
What is Identical (the same)?
The percentage that each square in a punnett square represents
What is 25%?
Name two human traits that could be inherited from a parent?
Examples: hair color, eye color, height, skin color, freckles, etc...
Tightly compacted DNA in the nucleus. Humans have 46 of these.
What are Chromosomes?
The type of plants Gregor Mendel worked with.
What are Pea Plants?
An example of asexual reproduction where the cut off pieces of the organism grow into a new organism.
What is Fragmentation?
A black chicken (BB) is crossed with a black chicken (Bb). What percentage of offspring will be black?
What is 100%
The corresponding DNA strand for the following:
ATCGGCGA
What is TAGCCGCT?
The two options for an allele in genetics.
What are dominant and recessive?
The physical trait observed in an offspring. What we see from genotype.
What is Phenotype?
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-
What is Dominant
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?
What is 25%?
How many parents are involved in asexual reproduction?
What is One?
Genetic make up of the individual, represented by a set of letters.
What is genotype
Genotype represented by two capitol letters.
What is Homozygous dominant?
This process results in a zygote. Only occurs in sexual reproduction.
What is fertilization?
Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
What is Ee?
Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. This is the genotype for both parents.
What is heterozygous?
