Asexual reproduction. This is mainly because the runner comes from one parent thus there is no genetic diversity in the offspring. They are clones.
Answer:
A)
Hh * hh
Hh, Hh, hh, hh
Out of four two calves are horned. Thus ratio of horned calves is
B)
Hh * Hh
HH, Hh, Hh, hh
Out of four one calf is horned. Thus ratio of horned calf is
C)
Hh * hh
Hh, Hh,hh, hh
Out of four two are polled . Thus ratio of polled calves is
Explanation:
Allele for dominant polled /hornless cattle is H
Allele for recessive horned cattle is h
A) Polled bull X horned Cow A ----> horned calf
This signifies that the polled bull is heterozygous with genotype Hh
Hh * hh
Hh, Hh, hh, hh
Out of four two calves are horned. Thus ratio of horned calves is
B) Polled bull X polled Cow B ----> horned calf
Both Bull ad cow are heterozygous with genotype Hh
Hh * Hh
HH, Hh, Hh, hh
Out of four one calf is horned. Thus ratio of horned calf is
C) Polled bull X horned Cow C ----> polled calf
Hh * hh
Hh, Hh,hh, hh
Out of four two are polled . Thus ratio of polled calves is
The answer is e. Myoglobin has a single
polypeptide chain so it has 10, 20, 30 and 40
structure.
Myoglobin is an iron and an oxygen binding
protein. It has a single polypeptide chain.
Proteins with the single polypeptide chain
cannot have quaternary (40) structure. 40
structure of proteins includes an arrangement of
multiple folded polypeptide chains (subunits) in
a multi-subunit complex. Therefore myoglobin
cannot have 40 structure as the single chain
polypeptide. All other choices are correct.
