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.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
