Question

4. Look at the picture of the leaves on pg. 161 of your textbook. They should all have the same alleles for their genes. However, what is the likely explanation for the numerous differences in phenotypes?

Answer 1

3. False

All human characters doesn't follow mendels rules.only dominant and recessive rule is followed.

Example:

Mendel proposed that all units of inheritance are passed or given on to offspring unaltered. Unstable alleles are an significant exception to this rule. The phenotype of an individual is not left with inheriting a particular set of parental genes.

(As figure is not provided,answer may not be accordingly)

The phenotypic variation in leaves might be pheontypic plasticity where the alterations in shape ,size and thickness of leaves occurs depending on surroundings and environment.Leaves are especially plastic, and their development might be adjusted by light levels. Leaves developed in the light will in general be thicker, which augments photosynthesis in direct light; and have a littler region, which cools the leaf all the more quickly (because of a more slender limit layer). On the other hand, leaves developed in the shade will in general be more slender, with a more prominent surface zone to catch a greater amount of the restricted light
