For Mendelian traits, ALL members of the F1 generation are expected to resemble the parent with the dominant trait. For cytoplasmic traits, the members of the F1 generation are expected to resemble the mother, with potential for variation due to the genetics of the cells from which the eggs developed. True/False

Bailey · Answer 1

True

Explanation:

Mendel's law of dominance states that in a hetero-zygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both gene contributing to a phenotype, the dominant allele will be expressed exclusively

In case of cytoplasmic inheritance, distinct maternal effects are observed. There is more contribution of cytoplasm to the zygote by female parent than male parent and we know generally that ovum contributes more cytoplasm to the zygote than sperm.
