Answer:
um feed is what you eat and feed stuff is what you use to make the stuff you eat
Explanation:
Answer:
Given,
RR and Rr = Red flower
rr = white flower
Homozygous condition means that both the alleles for the gene are either recessive or dominant alleles. Heterozygous condition means that one allele is recessive and other allele is dominant.
If a homozygous red flower geranium (RR) is crossed with a homozygous white flower geranium (rr), the Punnett square would be :
R R
r Rr Rr
r Rr Rr
A) Molecular clocks help to measure the number of changes and mutations which accumulate in the gene sequence of different species over a period of time.
B)It is based on the fact that genetic mutations although random, occur at a relatively constant rate. Evolutionary biologists use this information to deduce how species evolve and determine when two species diverged on the evolutionary time line.
It is useful in the study of variations in selective forces.
It also facilitates establishing the dates of phylogenetic events including those not documented by fossils.
The molecular clock technique is an important tool in molecular systematics. It helps to determine the correct scientific classification of organisms by deriving information from molecular genetics.
