the chance of the offspring inheriting allele for a widow's peak from either parent is ____

If two heterozygous individuals are crossed, the chance of the offspring inheriting an allele for a straight hairline from either parent is ________

the chance of the offspring being homozygous dominant is ____ and the chance of being homozygous recessive is _____

the chance of the offspring being dominant phenotype is ____ and the chance of having the recessive phenotype is _____

Thank you for you help:)

Explanation / Answer

The chance of the offspring inheriting allele for a widow's peak from either parent is 1/2

A widow's peak is a dominant trait in which V shape dips down along the hairline. As widow’s peak is a dominant trait, one allele is enough to cause the disease. So, offspring has 1/2 chance of getting this trait from either parents.

If two heterozygous individuals are crossed, the chance of the offspring inheriting an allele for a straight hairline from either parent is 1/4

The chance of the offspring being homozygous dominant is 1/4 and the chance of being homozygous recessive is 1/4

The chance of the offspring being dominant phenotype is 3/4 and the chance of having the   recessive phenotype is 1/4.
