A black feathered cow bird hatches a chick that is white due to a mutation in the gene that makes the black pigment. This white bird manages to mate with a wild type black bird. The offspring are iridescent grey. Explain briefly how this mating resulted in the new color of cowbird.

Mutation induced incomplete dominance of the alleles

Explanation:

Mutation refers to any change in the nucleotide sequence of an organism's genetic material (DNA). In this question, the change affects the feather colour of a bird i.e. making a black feathered bird produce a white chick. The white chick produced can be said to be a "MUTANT" because it is a result of mutation in the feather colour gene.

When this mutant white feather colored bird mates with a wild type (naturally) black feathered bird, iridescent grey offsprings emerge. The change in colour can be attributed to INCOMPLETE DOMINANCE. This is because the mutation that occurred caused a change in the alleles making dominant allele incompletely dominant over the recessive pair. Hence, a third phenotype (grey), different from the two parental phenotypes (black and white), is produced.

cell regulation is conducted by special proteins.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
