What else can I help you with?
Emmer wheat Triticum discoccum has a somatic chromosome number of 28 and rye Secale cereale has a somatic chromosome number 14 Hybrids produced by crossing these cereal grasses are highly steril?
The hybrids produced by crossing emmer wheat (with 28 chromosomes) and rye (with 14 chromosomes) would have an uneven number of chromosomes (21), leading to genetic imbalance and sterility. This is because the chromosomes cannot pair correctly during meiosis, resulting in non-viable gametes and ultimately sterile offspring.
What is second filial generation?
Parent generation is the term used to refer the male and female parents used in making hybrids. These parental strains is purified is obtained by repeated cycles of self fertilization. Filial 1 (F1)generation is the one resulting from the cross of such two selected parent generation. this generation express high degree of uniformity(Hybrids) The progeny/generation derived from Filial 1 generation is termed as filial 2 generation(F2). this generation could show very high degree of variation from progeny to progeny depending upon the parental generation used.
What are the offspring of two different organisms called?
The offspring of two different organisms are called hybrids. These offspring inherit traits from both parent organisms.
What was the first generation of offspring in Mendels experiment?
The first generation of offspring from a cross is called the F1 generation.
What are hybrids for plants?
Each time Mendel studied a trait, he crossed two plants with different expressions of the trait and found that the new plants all looked like one of the two parents. He called these new plants hybrids because they received different genetic information, or different alleles, for a trait from each parent.
Generation of all hybrids produced by crossing two pure organisms?
F1 Generation
Hybrid organisms prodused from a cross between two pure-breeding organisms belong to which generation is F1?
Hybrids from a cross of parental (P) generation, of homozygous parents (one is homozygous recessive, the second one is homozygous dominant) do belong to F1 generation, yes. Their genotype is heterozygous.
What are offspring produced by parents that differ in one or more traits are called what?
Offspring produced by parents that differ in one or more traits are called hybrids. These hybrids can exhibit a combination of characteristics from both parent organisms, which may result from crossing different species or varieties within a species. In genetics, this concept often relates to the study of inheritance patterns and phenotypic expression.
How are hybrids are produced?
hybrids are produced when two different species interbreed
What did mendel call the offspring of the first filial generation?
Mendel called the offspring of the first filial generation "F1 hybrids" or "first filial generation." These offspring result from crossing two true-breeding parents with different traits.
Which characteristics was true of Mendel's F1 generation plants?
They were all hybrids
What are all offsprings f1 called?
All offspring from the F1 generation, which is the first filial generation resulting from a cross between two parental (P) organisms, are typically referred to as F1 hybrids. These hybrids are often genetically uniform and display traits that are a combination of the parental traits. If further crosses are conducted, the next generation of offspring would be termed F2.
Who created hybrids?
Hybrids are organisms that result from the crossbreeding of two different species. In nature, hybrids can occur spontaneously, or they can be intentionally created through controlled breeding by humans. The specific individual who creates a hybrid would depend on the context in which the hybrid is being produced.
How do you produce hybrids?
Hybrids are produced by crossbreeding different two species and the new varieties of organisms are obtained Scientists are performing several experiments on plants as well as in animals and the desired product is thus obtained. This is how new species comes into existence . But this is prohibited in human beings to obtained hybrids using them.
Which characteristic was true of mendels generation plants?
they were all hybrids
Can organic vegetables and fruits be hybrids or does organic prohibit that?
Hybrids are the result of crossing varieties with each other to produce desired characteristics. They are not prohibited by organic certifiers.
