Answer:
A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ovum). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.
Explanation:
Answer:
Parent 1 genotype: Dd
Parent 2 genotype: Dd
Child 1 (dimples): Dd or DD
Child 2 (no dimples): dd
Child 3 (no dimples): dd
Explanation:
No dimples (d) - recessive
D (dimples) masks d (no dimples), therefore D (dimples) is expressed
Answer:
Biology is the science that studies life, and living things, and the evolution of life.
Explanation:
Living things include animals, plants, fungi (such as mushrooms), and microorganisms such as bacteria and archaea. Biology examines the structure, function, growth, origin, evolution, and distribution of living things. It classifies and describes organisms, their functions, how species come into existence, and the interactions they have with each other and with the natural environment.
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
