Answer: Always and always
Explanation:
Within any large animal population there is always a variety of traits seen in the population. When there is a large number of individuals in a population then there are chances that there a genetic diversity.
Sexual reproduction in the organism can lead to the genetic variation in the organism. There are chances to have more variation in the population having more organism.
Two different organism are genetically different and there are variety of traits seen in the two animals that belongs to different species.
Answer:
- Parental cross = Cch x chch
- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio
Punnett square:
ch ch
C Cch Cch
ch chch chch
Explanation:
A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.
The best approach to curbing excessive human population growth is extensive public education programmes and distribution of family planning methods in countries with high fertility rates. Most countries with high fertility rates have large numbers of the population living in poverty and this limits the access people may have to modern methods of contraception.
Answer:
The correct answer will be option-D
Explanation:
The light-dependent reaction of the photosynthesis process takes place in the thylakoid membrane of the chloroplast.
The electron transport chain takes place in the thylakoid membrane which leads to the flow of protons out of the membrane producing the disequilibrium in the membrane potential across the membrane. This difference in the membrane potential results in the flow of protons which help in the synthesis of ATP.
If the thylakoid membrane is punctured will disturb the membrane potential across the membrane. This will lead to the disturbance in the flow of protons into and out of the cell which will affect the synthesis of ATP by ATP synthase enzyme.
Thus, option-D is the correct answer.
