Beacuse men only have one X chromosome so beacuse colourblindness is found on the X chromosome then if the X inherited from his mother contains the allele for colourblind then he will be colourblind. women have two X chromosomes so even if they inherit one colourblind allele then if the other X contains a normal vision allele then they will be able to see normally.
Answer:
Parents: yellow, entire petals (CC FF) × white, fringed petals (cc ff) F1 (Cc Ff)
For the cross of a heterozygous F1 individual (Cc Ff) with a homozygous recessive
individual (cc ff) we would expect a phenotypic ratio of 1:1:1:1 for the different phenotypic classes.
Phenotype Observed (O) Expected (E) (O - E)2/ E or ( 2)
Yellow, entire 54 43.75 2.40
Yellow, fringed 58 43.75 4.64
White, entire 53 43.75 1.96
White, fringed 10 43.75 26.0
Total 175 175 35
Degrees of freedom = 4 - 1 = 3. The chi-square value is greater than 12.838 for a probability value less than .005, or 0.5% that random chance produced the observed ratio of California poppies.
B .t is unlikely that random variations produced the observed ratio.

The required answer is given below:
Explanation:
This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.
Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.
Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.
Answer:
If the birth rate is greater than death rate.
