In shorthorn cattle, coat color may be red, white, or roan. roan is an intermediate phenotype expressed as a mixture of red and white hairs. for this problem, use "a" to indicate the allele that produces red hair, and "a" to indicate the allele that produces white hair. the following phenotypic data are obtained from various crosses: cross 1: red × red → all red cross 2: white × white → all white cross 3: red × white → all roan cross 4: roan × roan → 1/4 red: 1/2 roan: 1/4how is coat color inherited? by incomplete dominanceby recessive epistasisby dominant epistasisby multiple alleleswhat are the genotypes of parents in cross 1? ( check all that apply)

- Incomplete dominance

- In the first cross, both parents are homozygous dominant for the red trait.

Explanation:

Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.
