In 1-3 sentences each define the follwing terms:
genotype, phenotype, homozygous, heterozygous, dominant, recessive, epigenetics
As alternative form of a single gene is known as
parental, dihybrid, reciprocal, allele, or recessive
The human traits described above are said to be controlled by a single gene. Using the character “earlobe attachment”, perform a genetic cross between a heterozygous mother and a homozygous recessive father. Use a Punnet Square following this gene notation: E for dominant allele; e for recessive allele

- A gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a husband and wife, who are both carriers of the sickle-cell anemia allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele being equally likely. Complete parts a) through c) below. a) Genes are always written with the dominant gene first. Therefore, there are two instances the offspring could have genotype Ss (one if the mother contributes the dominant allele and the father contributes the non-dominant allele; and one if the father contributes the dominant allele and the mother contributes the non-dominant allele). List the other two possible genotypes of the offspring. (Use a comma to separate answers as needed.)arrow_forwardExplain how twins could have the same genetic material but not look exactly the same or have the same chances of suffering from diseases such as cancer.
