In order to reproduce, many flowering plants use external agents, such as insects or birds, to aid in the pollination process. The plants put out colorful and fragrant flowers to attract the insects to aid in the pollination process. Insects like butterflies are highly sensitive to the bright colors. They get attracted to the flower on seeing the bright color. Birds are sensitive to both color and odor. They visit those plants that either have colorful or fragrant flowers. Thus become carriers of the pollen grains and cause pollination.

A farmer crossed a yellow maize plant (Yy) with another yellow maize plant (YY). He planted 200 seeds from this cross. How many
Vladimir [108]

Answer: 200 seeds will be yellow.

Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.

In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., <u>200 seeds will be yellow</u>.

In horses, the gene for black coat color is dominant over the gene for brown coat color. The gene for long manes is dominant ove
Gwar [14]

Answer:

3/16

Explanation:

Given,

Black coat color is dominant over brown coat color.

Long mane is dominant over short mane.

BBLL X bbll =

F1: BbLl = Entire progeny has black color and long mane

BbLl progeny will produce BL, Bl, bL and bl gametes. When they interbreed, the resultant F2 progeny will be in 9:3:3:1 dihybrid ratio. Hence in F2,

BBLL : BbLL : bbLl : bbll = 9 : 3 : 3 : 1

3/16 progeny will have bbLl genotype hence 3/16 progeny will have brown, long mane.

From an evolutionary perspective, what adaptive value do mirror neurons have?
Akimi4 [234]

Mirror neurons are said to be the factors behind social imitation. Neurons are the main cell of the nervous system which is responsible for communication of organs and control of many bodily functions. In an evolutionary standpoint, mirror neurons are an advantage because humans are able to replicate and imitate skills, behaviors and practices which they find beneficial and advantageous in the wild. Among their social peers, mirror neurons help these individuals practice social inclusion through culture, values and practices for increased group cohesion and cooperation.
