1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.
Option D
<h3><u>
Explanation:</u></h3>
Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.
He crossed them to get all tall plants in Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is of the total population of F2 generation.
Answer:
The correct answer is -
A. a, c, g
B. e, b, f & d
Explanation:
Part A- the options a, c, g are the options that show mutation or replacement by a single base change
a) Phenylalanine: UUU UUC
Leucine: UUA UUG
Only one base change
c) Alanine: GCU GCC GCC GCG
Thr: ACU ACC ACA ACG
only one base change
g) Prolin: CCU CCC CCA CCG
Serine: UCU UCC UCA UCG
Part B:
All other replacements will not be consistent with the Genetic Code if single base substitutions occur in option e, b, f & d
1. Northern Hemisphere is having its summer solstice because it is tilted towards the Sun receiving the most direct sunlight of the year during the longest day. The Southern Hemisphere is having its winter solstice, the shortest day of the year, because it is tilted away from the Sun.
