The egg contributes more cytoplasm than the sperm to the zygoterelationship between allele frequency and genotype frequency (Nucleus or mitochondrion)nuclear genome: alleles frequencies are not the same as genotype frequencies because they are packages in groups of two (diploid). Long-standing issues with urban expansion and beachfront development continue to displace nesting females, artificial coastal lighting lures thousands of hatchlings to their deaths, and shoreline erosion and the erection of sea walls contribute to the disappearance of historic nesting grounds. 4 and 0. a third allele of same gene, dominant over both of the others, has an initial frequency of 0.
