Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant.
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).
Answer:
Conduct a test cross with a purebred recessive plant.
Explanation:
Verified after test was graded within ody ssey ware system as question # 10.
The questions wording: You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?
Answer:
A. limbic system
Epidermis
I think you coppied and pasted it one to many times, so I hope it's just one answer.
Ultraviolet light primarily causes the production of Vitamin D3 in the cells of the epidermis. Smaller amounts are also produced in the dermis and hypodermis.
Ultraviolet light stimulates the production of vitamin D3 primarily in the cells of the epidermis, which is the outermost layer of your skin. Additionally, a smaller amount of vitamin D3 production happens in the deeper layer known as the dermis and the hypodermis. However, most references will identify the epidermis as the main site for this production because it has the highest exposure to sunlight, which is crucial for vitamin D3 synthesis.

Answer:
Themoderator band is a bundle of cardiac muscle fibers connecting the interventricular septum to anterior papillary muscles.
Explanation:
The moderator band or septomarginal trabecula is a muscle band of heart tissue that is located in the right heart ventricle. It is well defined in sheep and some other species, and often stretches from the base of the anterior papillary muscle to the septum of the ventricle.
A moderator's primary function is to foster interaction among the forum members. The moderator exposes the respondents one to another and continues to update the forum on new members.
