In the f1 generation of a mendelian cross,
a. only the dominant trait is visible.
b. only the recessive trait is visible.
c. neither the dominant nor recessive trait is visible.
d. both the dominant and recessive traits are visible.

Correct answer choice is:

A. Only the dominant trait is visible.

Explanation:

F1 stands for "filial". The F1 generation comprises all the offspring which they got from the parents. F1 hybrids are utilized in genetic science, and in selective breeding, wherever it should seem as the F1 crossbreed. Therefore, only the dominant trait is visible.

A. only the dominant trait is visible.

Monohibrid is a cross between two individuals of the same species with a different characteristic. This monohibrid cross is closely related to Mendel I law or what is called the law of segregation. This law reads "In the formation of gametes, paired genes will be separated (segregated) into the two gametes (sex cells) formed".

Gregor Mendel first learned about the nature of monohibrid when crossing experiments on peas (Pisum sativum). From this monohibrid crossing Mendel formulated Mendel I's law (the law of segregation).

In fact, during Mendel's life, no substance was known to determine inheritance (genetic material). Mendel said that genetic material is only a determinant factor or abbreviated as a factor.

Mendel's Law I applies to F1 x F1 gametogenesis that has heterozygous genotype. Genes located in the same locus on chromosomes, when gametogenesis, the sealel genes will separate, each going to one gamete.

The first filial (F1 is the result of a cross from parents (parent) so as to produce the first offspring or children.

Heredity is the inheritance of physical characteristics, biomass and behavior from a living creature to its offspring. This inheritance is controlled by a genetic substance called DNA (deoxyribo nucleic acid = dioxyribo nucleic acid), which is present in genes. Genes are contained in chromosomes, which are located in the nucleus of cells.

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.
