The second-generation theory of the gene: The second-generation theory entails the filial generation principles in genetics by Gregor Mendel. The filial generation involves crossing two individuals of the first (F1) filial generation. Gregor Mendel described the principles of filial generations in genet...
Which generation is always heterozygous in a Mendelian monohybrid cross? a. F3 b. P c. F2 d. P2 e. F1 What are alleles in biology? A man with type O blood has a sister with type AB blood. What are the genotypes and phenotypes of their parents?
This first generation is called "F1." When he crossed two purple-flowered plants from the F1 generation, they produced 75% purple-flowered plants, and 25% white-flowered plants. This second generation is called "F2." He determined that the white-flowered trait was recessive. It was ...
to low-throughput targeted sequencing projects; higher-throughput DNA sequencing technologies based on fundamentally different methods have emerged in the last decade. Called next-generation sequencing (NGS), these massively parallel technologies have revolutionized t...
The trait whose genes are present, but does not appear in F1 generation is a: A. recessive trait. B. dominant trait. C. codominance. How many recessive alleles for a trait must an organism inherit to show a trait? What is the relationship between genes and alleles? What is the phenotype...
A very alarming study reported transgenerational effects due to the exposure to microplastics .[16] Rodents who were given contaminated water during gestation and lactation showed liver changes and altered intestinal microbiota; in addition, the F1 generation showed similar hepatic alterations and altered...
The resulting F1 generation all had red eyes; however, Morgan suspected that the white-eye trait was still present but unexpressed in this hybrid generation, like a recessive trait would be. To test this, Morgan then crossed males and females from the F1 generation and observed a 3:1 ratio...

Fill in the blank: When an organism expresses both alleles equally, this is known as ___. What is the term that is used to refer to the genotypes of offspring from two individuals? a. F1 generation b. P generation c. zygotes. d. phenotypes e. F2 generation How many possi...
Given that the individual has a dominant phenotype, is it possible to determine its genotype? Which of the following best describes the mother s genotype? A) Homozygous recessive B) Heterozygous C) Homozygous dominant D) Heterozygous and Homozygous dominant What are alleles in biology? In a mon...
