Answer:
In favourable environments you might find birds laying more eggs, and a greater likelihood of multiple successful clutches. There are also birds like Bald Eagles, that start mating in early January and can lay eggs before Spring officially comes. 13. Food Availability. The amount of food available has an affect on bird mating cycles.

Explanation:
Given:
Brown allele (B) is dominant over the white allele (b).
It will be assumed that the alleles are not related to the X and Y chromosomes.
See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)
For both parents hetero-zygous,
P1:
Genotype: Bb (100%)
Phenotype: brown (100%)
F1:
Genotypes : BB, Bb, bB and bb in equal proportions, i.e.
BB (25%), Bb (50%), bb (25%)
Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)
Answer:
The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.
Explanation:
In the eukaryotic cell, telophase is the final stage in meiosis and mitosis. In this step, the effects of prophase and prometaphase are reversed. This is the forth stage and a nuclear envelope forms at each pole. The spindle dissolves and the chromosomes uncoil, cytokinesis begins. The cell continues to enlogate.
For humans, we have 19,000 protein-coding genomes. For every gene, there are 2 alleles. This means that humans have 38,000 alleles (19,000×2=38,000).
