A mutation in the LDL receptor gene can cause a dramatic rise in serum cholesterol.
At the chromosome levels males are homogametic.
Which of the following is true about the rare condition of males who are XX and females who are XY:
Which of the following is true about homosexuality?
More than 100 genes affect pigmentation in skin hair and irises.
Which of the following hunger response hormones decreases appetite but increases digestion?
Melanocytes contribute to skin color;
The mechanism of genomic imprinting involves:
Genomic imprinting has implications for understanding early human development. It suggests that for mammals, two opposite sex parents are necessary to produce a healthy embryo and placenta.
Considering color detection humans are classified as?
According to some genetic researchers, the palindromic and repetitive sequences found in the Y chromosome.
A biblical view of race shows that all races are equal because they are all of one blood in Adam.
Which of the following hunger response hormones increases appetite?
Which of the following are polygenic multifactorial traits?
Epigenetics plays a role in controlling weight gain as shown in experiments with genetically determined obese mice. Obese female mice were able to decrease obesity in their offspring by eating a diet rich in:
Which of the following is true about the “X” and “Y” chromosomes?
This famous discoverer of the DNA structure made racist comments in the 1990s based on the idea that certain people groups were biologically inferior.
5-alpha reductase deficiency is an autosomal recessive condition leading to delayed conversion of testosterone to DHT causing delayed development of a penis until puberty in some XY individuals, and contributes to a condition known as;
Given that the SRY gene is dominant, Mendel’s law of segregation predicts that human populations should have;
In general there is no male-to male transmission of X- linked traits.
Even though Mendel’s laws are very helpful to understanding genetics, simple mendelian genetics does not explain well most of genetics because; Many phenotypic traits are also multifactorial (influenced by the environment)
Prader-Willi syndrome is a genetic disease caused by imprinting. More specifically this involves:
Simple mendelian single gene genetics explains skin color.
A person who is male but who prefers women’s clothing and does not have an abnormal XY or XX condition is known as;
In mother’s who are carriers for colorblindness even though they are not color blind some of their individual eye cone cells can express the trait. Also in female Calico cats the genes which produce color are found on the X chromosome and each hair cell expresses one X allele or the other giving rise to a random pattern of color in their fur. In both cases this is an example of:
