Question

squash can be yellow or green. when two yellow squash are crossed, the offspring are always yellow. when two green squash are crossed, sometimes the offspring are green and sometimes they are yellow. which must be true about the squash color gene? the yellow allele is dominant the green allele is dominant both the green and the yellow allele are dominant both the green and the yellow allele are recessive

Explanation:

Dominant alleles are expressed in offspring even when a recessive allele is present. Since two yellow - squash crosses always produce yellow offspring, yellow is likely dominant. When two green squash are crossed and sometimes yellow offspring result, it implies that green squash can carry a recessive yellow allele.

Answer:

The yellow allele is dominant
