Answer No 1:
The genotype of the red beans will be RR. As red is the dominant trait, it will be written in capital letters.
A dominant trait is the one which suppresses the effect of a recessive trait. A recessive trait is the one which gets masked by the dominant trait.
Answer No 2:
The genotype of the white beans will be rr. As white beans are considered as a recessive trait, hence it will be written in small alphabets.
As explained earlier, a recessive trait gets marked by a dominant trait. For a recessive trait to express its phenotype, both the alleles of a gene should be recessive.
Answer No 3:
The genotype of the pink beans will be Rr.
r r
R Rr Rr
R Rr Rr
Answer No 4:
<em>The correct option is C. </em>
Incomplete dominance can be described as a trait which occurs when a dominant trait is not dully dominant over the recessive trait. As a result, offsprings are produced which have a phenotype which is a blending of both the dominant and recessive phenotypes. Such an effect is known as incomplete dominance.
Answer:
a stack containing multiple flattened, disk-shaped membranes called cisterns
Explanation:
Adenine pairs with Thymine (A=T) AND Cytosine pairs with Guanine (C=G)
Answer: Genetic variability is beneficial for the survival and adaptation. But a flaw in DNA Replication Control or check may leads to the death of cell or may contribute in the disease or cancer.
Explanation:
Almost every species comes with the diversified collection of genes (genome). And some of the diversity comes from the spontaneous mutation but it occurs on a very low frequency. The genes either express constitutively or occasionally for an important task like genes responsible in the generation of ATP by glycolysis, tricarboxylic acid cycle, electron transport chain etc. While some of the genes are inducible that is only activated in a response to an external stimuli. Genetic variations in inducible genes might account for the adaptability or negligible change in a species genetic expression but genetic variation in constitutive or house keeping genes leads to cancer cell formation or even cell death. like mutation occur in p53 genes dysregulate the cell cycle or mutation occur in DNA polymerase enzyme that is responsible for the incorporation of NTPs (nucleotide tri-phosphates) according to wobble base pairing rule in order to make a complementary new strand from the old or parent strand, will eventually leads to cause mutations ultimately results in cell death or cancerous cell formation.
