Some of the evidence comes from fossils, and some comes from studies that show how similar living things are to one another. By the 1930s, scientists had also learned about genes. As a result, they could finally explain how characteristics of organisms could pass from one generation to the next and change over time

plant species A has two alleles for leaf color. if plant species B has four alleles for leaf color, how will the two species dif
Yanka [14]

Plant A would have one allele from each parent, so the leaf color will be the dominant one.

Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.



Hope it helped,

TEA [102]

Answer:

C) Clone the plant

Explanation:

Cloning is the process by which genetically identical offsprings are obtained naturally or artificially. In nature, genetically similar individuals or offsprings are obtained from asexual reproduction.  

If a horticulturist succeeds in having a single plant with the desired trait than to establish a line of such plant she should clone the plant so that the plants which are obtained after cloning have the same traits which were present in the parent plant. Therefore the correct answer is C.

In a population of Mendel's garden peas, the frequency of the dominant A (yellow flower) allele is 80%. Let p represent the freq
k0ka [10]

Answer:

C) 64% AA, 32% Aa, 4% aa

Explanation:

The frequency of dominant allele A is = 80% = 0.8

Since the population is in Hardy-Weinberg equilibrium, p+ q =  1

Here, p= frequency of dominant allele

q = frequency of recessive allele

Given, p= 0.8

So, q = 1-p = 1-0.8= 0.2

Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%

Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%

Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%
