Module 2 Flashcards
If a child receives an allele for blue-eyes and an allele for brown eyes, then the child is
heterozygous for that trait.
Tissues are replaced through a process called
Mitosis
Traits are determined by
Pairs of genes.
Identical twins are also described as
Monozygotic.
In comparison to the average male population, individuals with Klinefelter’s syndrome
Produce less testosterone than normal.
People who bear one dominant & one recessive gene for a trait are
Called “carriers” of the recessive gene.
A zygote that divides into 2 cells that separate results in
monozygotic genes.
Heredity is defined as
One’s nature, & is based on biological transmission of traits and characteristics.
A woman who gives birth to dizygotic twins
Has an increased chance of giving birth to twins in future pregnancies.
A human cell contains how many chromosomes?
46.
Sperm cells carrying the Y chromosome will
Contain less genetic material than those carrying the X chromosomes.
Individuals with Down syndrome
Have moderate to severe cognitive impairments.
With amniocentesis
fluid is tested from the “sac” containing the fetus.
Down’s Syndrome is linked to
Abnormalities of the 21st pair of chromosomes.
Chromosomes contain thousands of segments called
Genes.
