Answer:
Heterozygous
Explanation:
- A dominant trait is the one that expresses itself over the recessive trait, therefore for a recessive trait to express itself, an organism must have both the alleles as recessive for a given genotype.
- In the question, it is given that the lack of horns is dominant over presence hf horns.
- If we symbolize lack of horns as H and presence of horns as h,then :
- the genotype of the bull without horns needs to be determined
- the horned cow must be hh as this is a recessive trait
- it is given that out of four offspring one is horned, this means that this horned offspring must be hh and since the offspring inherits one allele each from the parents, one h must be coming from the cow and the other h from the bull and hence, we can conclude that the bull must be Hh i.e heterozygous .
