What is the genotype for widows peak?

The genotypes WW and Ww will produce a widow’s peak (the dominant phenotype) and the ww genotype will produce no widow’s peak (the recessive phenotype).

How many individuals would you expect to be homozygous dominant and heterozygous for this?

How many individuals would you expect to be homozygous dominant and heterozygous for the trait? q2 = 0.25 homozygous dominant = p2 heterozygous = 2pq q = 0.5 = 0.52 = 2(0.5)(0.5) p = 0.5 = 0.25 = 0.5 0.25(500) = 125 individuals 0.5(500 ) = 250 ind. 3.

What do your results indicate about the importance of population size as an evolutionary force?

1. What do your results indicate about the importance of population size as an evolutionary force? When a population is very large, there is more diversity. When there is a small population with only a couple of offspring reproducing at each generation, and then eventually, there will be no diversity at all.

What major assumptions were not strictly?

The major assumption that was not strictly followed is that there can be no selection.

Are dominant or recessive alleles easier to remove by selection?

It is actually much easier to select against a dominant allele than it is to select against a recessive one, because if an individual has a dominant allele, the trait is exhibited.

Why do recessive alleles not disappear?

While harmful recessive alleles will be selected against, it’s almost impossible for them to completely disappear from a gene pool. That’s because natural selection can only ‘see’ the phenotype, not the genotype. Recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools.

How do you know if a trait is recessive or dominant?

If both parents do not have the trait and the child does, it is recessive. If one parent has the trait and the child does or does not, it is dominant.

How can an offspring inherit a recessive trait?

Explanation: The offspring can inherit a recessive trait if both of its parents are heterzygous for the dominant allele. This mean they have one dominant trait and one recessive for the same gene.
