What did Mendel's cross pollination of pea plants prove
pashok25 [27]

Answer: The correct answer is- D certain factors are dominant and other factors are recessive.

Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.

For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.

When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).

Thus, option D) is the right answer.

You inherited your mother's crooked nose and her recipe for chocolate chip cookies (both favorable traits). Which trait will be
SIZIF [17.4K]

Answer:

b.the recipe because it can be passed on to all relatives

Explanation:

A crooked nose is a genetic trait and can be passed to the progeny via genes only. Sexually reproducing organisms such as humans experience segregation of traits during gamete formation. Therefore, crooked nose inheritance is a chance factor regulated by the inheritance of genes and the segregation of alleles. On the other hand, a recipe for chocolate chip cookies can be shared with all the relatives and other individuals of the population by any means without any conditions. Therefore, a recipe will spread more quickly through the population.
