I don't know, maybe because of the way we see animals. Not as our equal parts
Answer:
Genotype ratio: 1, 1:1, 1:2:1
Phenotype ratio: 1, 3:1
Explanation:
Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.
For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:
P: AA x AA
F1 : all of them are AA
The same is with aa x aa (all of the offspring are with aa genotype)
P: AA x Aa
F1: AA Aa AA Aa (genotype ratio 1:1) (phenotype ratio 3:1)
The same genotype ratio is in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)
P: Aa x Aa
F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)
P: AA x aa
F1: Aa Aa Aa Aa (1)
Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.
<h3>
What is competition?</h3>
If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.
As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."

Answer:
mitochondria DNA (mtDNA) has maternal inheritance
chloroplast DNA (cpDNA) has paternal inheritance
Explanation:
DNA is deoxyribonucleic acid is the molecule responsible for encoding the genetics instructions used in the development and functioning of all known leaving organism.
in humans mitochondria DNA (mtDNA) has maternal inheritance and
chloroplast DNA (cpDNA) has paternal inheritance
