Skin Color
The thing that determines skin color.
What is skin pigment?
The Father of genetics.
Who was Mendel?
To determine the outcome of genetic crossings.
What is the punnett square used for?
Allele that masks the effect of another allele.
What is dominant?
This type of albinism primarily affects the eyes.
What is ocular albinism?
The term used to describe a group of pigments that make up skin, hair, and eye color.
What is melanin?
Genes that can be hidden or covered up by another gene.
What are Recessive genes?
Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygous recessive (e), this is the only possible genotype of the offspring.
What is Ee.
Two traits that could be inherited from a parent.
What are hair color, eye color, height, skin color, freckles, etc...
This form of albinism affects the eyes, hair, and skin color.
What is oculocutaneous albinism?
The cells that make melanin.
What are melanocytes?
Different forms of a gene.
What are alleles?
Percentage of heterozygous offspring when 2 heterozygous parent are crossed.
What is 50%?
Passing of traits from parents to offspring.
What is heredity?
OCA follows this type of inheritance pattern.
What is autosomal recessive inheritance?
The affect of the absence of melanin.
What is albinism?
Offspring of the P generation.
What is the F1 generation?
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. This percentage of the children will NOT have dimples.
What is 25%.
The sorting of chromosomes during sexual reproduction, determines this.
What are traits are passed on to the offspring?
This symptom is more noticeable in African Americans and is visible from a distance.
What is irregular/lighter hair color?
The layer of skin associated with skin color.
What is the epidermis.
Inheritance of one trait has no effect on the inheritance of another
What is the law of independent assortment?
Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color?
What is Dark brown is dominant and white fur is recessive and Both parents are heterozygous?
This describes a factor that controls the traits.
What is a gene?
This form of albinism only affects Asians.
What is none!
