B.
DNA --> transcription. DNA is transcribed to mRNA.
mRNA --> translation. mRNA goes to rRNA (ribosomes) and translates the mRNA sequence. tRNA brings the correct amino acids.
Amino acids form a growing chain and the final product is a protein.
Answer:
Alleles of a gene are responsible for different traits
Explanation:
There are several variant of a gene which in pair leads to varied phenotypic characteristics or traits.
For instance, there are three alleles for blood group i.e A, B and O but there are in totality there are basic 8 blood groups including the categorization on the basis of Rh factor.
Likewise, there are several variations of skin color; however there are majorly six genes that are responsible for skin color.
So, basically alleles of a gene are responsible for different traits
True i think but i could be wrong. hope you get it right!
Answer:
Phenotypic ratio= 1:1
Genotypic ratio = 1:1
Explanation:
This is a monohybrid cross involving a single gene that specifies a color phenotype.
According to the question, WW, which is homozygous dominant i.e same allele is white while ww, which is homozygous recessive is black.
Hence a genotype Ww will possess a white phenotype since the W allele will mask the expression of w.
In a cross between a female and male with a a Genotype Ww and ww respectively. The parents alleles will be separated into gametes according to Mendel's law of segregation. (See attached image).
Ww will produce gametes W and w
ww will produce gametes w and w
The four possible offsprings will have Ww (2) and ww (2) genotypes. Hence two of them will be white while two will be black.
Hence, the phenotypic ratio will be 1:1 while the genotypic ratio will also be 1 Ww: 1 ww
