In birds, males have two copies of the Z chromosome (ZZ) and females have a Z chromosome and a W chromosome (ZW). Females transmit a Z chromosome to their sons and a W chromosome to their daughters, while males transmit a Z chromosome to both their sons and their daughters. Based on this information, which statement is true? A) A mutant phenotype due to a recessive Z-linked allele will be more common in males than in females. B) Males are hemizygous for Z-linked genes. C) Females who receive one Z-linked mutation are heterozygous carriers. D) A recessive Z-linked trait can skip a generation if it passes through a carrier (phenotypically normal) son. E) All of the above

Explanation:

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
