Study 1c Chromosomal Basis Inheritance in MCAT Biological and Biochemical Foundations of Living Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Which inheritance pattern is most consistent with a gene located on the Y chromosome?

ANSWER

Father-to-son transmission only. Y-linked genes pass solely from fathers to sons, as the Y chromosome is male-specific and not in females.

In a plant species, a recessive allele d causes dwarfism. A dwarf plant (d/d) is crossed with a heterozygous plant (D/d). Cytological analysis of the heterozygous parent reveals a reciprocal translocation between two nonhomologous chromosomes; the heterozygote is a translocation carrier but phenotypically normal. In the offspring, many seeds abort early, and among the surviving seedlings the ratio of normal:dwarf is close to 1:1. Which explanation best accounts for the observed seed abortion and the surviving phenotype ratio?
