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.
This is the gene cycle and if their mother has different gene then that will happen.
Answer:
The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized
Explanation:
During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.
