1. In cattle (R) is incompletely dominant over white (W) hides. Roan is the name of the color that results from the incomplete dominance. What are the
possible results if a white male is crossed with a roan female? Make sure to give genotypic AND phenotypic ratios in your answer.

Respuesta :

When white male (WW) is crossed with a roan female (RW), 2 roan (RW, RW): 2 white (WW, WW) offspring are produced.

What is genotype?

  • "The internal makeup of genes is called genotype."
  • The alternative form of gene is called allele.
  • The allele that is expressed in the generation is called dominant allele and the allele whose expression is masked and is only expressed if both of its copy is present is called recessive allele.

What is phenotype?

  • "The expressed characters are called phenotype."

What is incomplete dominance?

  • "In this condition both alleles of a gene are expressed, which will result in an intermediate or different phenotype."
  • Here, it is given that red (R) is incompletely dominant over white (W) hides, which means that when RR is crossed with WW it produces RW (roan color). So, when RW (roan color) is crossed with WW (white color) it produces RW, RW, WW and WW.

Hence, 2 roan (RW, RW) : 2 white (WW, WW) offspring are produced.
