The pesticide resistant plants are also called generally as genetically modified plants. These are the breeds in which the genes are altered so as to maximize the yield, become more resistant to diseases and pesticides and many more. Gene gun is a technology of genetic technology which alters the DNA and RN structure of plants and also their structures
Answer:
There are several ways to measure fitness; for example, “absolute fitness” measures the ratio of a given genotype before and after selection while “relative fitness” measures differential reproductive success — that is, the proportion of the next generation's gene pool that is descended from a particular organism
Explanation:
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
The answer is b. reptiles
Answer:
Góndolas.
Explicación:
El principal órgano reproductor que se utiliza en el proceso de reproducción y nacimiento del bebé son las gónadas. Las gónadas están formadas por ovarios y testículos que son responsables de la producción de óvulos en las hembras y espermatozoides en los machos. Cuando el óvulo de la hembra y el esperma del macho se fusionan, se forma un cigoto que se convierte en un nuevo bebé. Todos estos procesos ocurren dentro del feto de la hembra.
