If B represents the allele for black eyes (dominant) and b represents the allele for orange eyes (recessive), what would be the phenotypic ratio of a cross between a heterozygous black-eyed MendAlien and an orange-eyed MendAlien?a. 3 black : 1 orangeb. 1 black : 0 orangec. 1 black : 1 oranged. 0 black : 1 orangee. 1 black : 3 orange

1 black : 1 orange

Explanation:

The heterozygous black eyed MendAllen will have both type of alleles B and b. But B being dominant will express itself and the individual will be black eyed.(Genotype-Bb)During meiosis two types of Gametes will be produced by this individual. One type of gamete will have the dominant allele and other type will contain the recessive allele.The orange eyed MendAllen will produce only one type of gametes that will have the recessive allele. (Genotype-bb)

When the above stated individual will be crossed the following combination of allele will be seen:

Bb- Black eyedbb-orange eyed

Thus, the phenotypic ratio of offspring will be 1black :1 orange.

idk but if i had to take an educated guess i’d say a c d
