In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. In this question, the symbol B will be used for the bearded allele and B* will be used for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant to the allele for white coat (w). Answer the following questions relating to the crosses below: B*BWw male X B Bb Ww female What proportion of males are bearded and black? What proportion of females are bearded and black? B*B Ww male X B*Bb Ww female What proportion of males are bearded and black? What proportion of females are bearded and black?

![### Genetics Crosses in Goats: Bearded and Coat Color Traits
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. In this question, the symbol Bᵇ will be used for the bearded allele and B⁺ will be used for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant to the allele for white coat (w). Answer the following questions relating to the crosses below:
**Cross 1:**
\[ B⁺Bᵇ\ Ww\ \text{male} \ \times \ B⁺B⁺\ Ww\ \text{female} \]
