3 ACOSS: 1) The entire male part of the flower, made of the filament and anther, is called the. 3) There are two types of cells - sex cells, which have only one set of chromosomes (haploid), and, which have two sets of chromosomes (diploid). These are also known as somatic cells. 8) If 1st generation plants (all heterozygous) are allowed to self-pollinate, the offspring will have a 3:1 ratio of dominant to recessive traits. These offspring are known as the. 10) The process of creating sex cells for reproduction is called. 13) Once the egg cell of a plant is fertilized in the ovary, the baby plant will develop a seed around it. And the ovary will develop into a(n), to help protect / spread the seeds. 14) ost cells are body cells, such as blood, muscle, and skin cells. These cells have 46 chromosomes. But have only half the regular number of chromosomes. These cells are also called gametes. 15) Haploid sex cells (gametes) made on the male part of a flower (anther) are commonly called. 16) When a plant self-pollinates and produces only identical looking babies, these plants are said to be. 18) A portion of a chromosome that codes for a particular characteristic or trait is called a(n). 20) Body cells contain TWO sets of chromosomes (one from Dad / one from om), so they are called. 22) The male part of the flower where the pollen is made is called the. 23) Before cells can divide, the chromosomes make copies of themselves. The two copies are attached together at the centromere, and each is called a "sister". 24) Breeding pure-bloods over and over is dangerous, because the genes never mix with other genes. ixing genes is important, so a species has enough genetic to survive diseases or other hazards. 25) The study of heredity and genes is called. 26) If you have one dominant allele and one recessive allele, you can not be true-breeding. Instead you are considered a(n) - kind of like a gas/electric car. 28) Your outward appearance, or your, depends on your genotype (genetic formula). 29) The part of the pistil on a female flower called the helps capture and transport pollen to the ovary. 30) The female reproductive portion of a flower, called the, is made of three parts - stigma/style/ovary. 31) Humans come in all different sizes, colors, and shapes. These different ways to describe your appearance are known as. Each one might have two or more variations that make us all unique. 34) Inside a flower's, pollen (male haploid cells) fertilize eggs (female haploids) creating diploid cells. 37) The likelihood (chance) that an event will happen is known as. 38) When both alleles are dominant (WW) or both are recessive (ww), we say the alleles are. 39) When the pollen from the male part of a plant fertilizes a flower on the same plant, this is called. 42) Any living thing (like bees or birds), or other factor (like wind or water), that can help move pollen from the male part to the female part of a flower, is known as a(n). 44) When you receive something (like money) from someone else, we say that you it. The same is said when you get genes from your parents. 45) Sometimes when an organism has a heterozygous trait, the dominant allele doesn't take charge completely. Instead, the recessive allele gets to show itself a little. We call this dominance. 46) When pollen reaches the female portion of the plant (stigma), it travels downward, where it will fertilize a(n) in the ovary, and begin the process of creating a seed. 47) The pistil is made of three parts: the ovary where the eggs are located, the stigma that collects the pollen, and the - a tube that connects the ovary and stigma. 48) Another word for sex cells is. Pollen/sperm are examples for males, ovules/eggs for females.

4 49) A characteristic that has more than three different variations (traits) UST be controlled by two or more genes. We call characteristics that are controlled by two or more genes. 50) During eiosis 1, when the homologous chromosomes from om and Dad line up next to each other, the two closest chromatids can overlap and exchange sections (genes). This is called. DOWN: 2) The female gamete is known as an ovule. But we also commonly call it a(n). 4) When the pollen from the male part (anther) on one plant fertilizes the female part (stigma) on a different plant, we call this process. 5) is the passing of genetic information from one generation to the next - parent to offspring. 6) Hair color is one type of characteristic for you. So is face shape. Each characteristic can have different forms or aspects, such as brown eyes or blue eyes. Each form is a different for that characteristic. 7) When a homozygous dominant father is bred with a homozygous recessive mother, the babies in the (two words) are look like the dominant trait, but are all hybrids in their genotype. 9) If your genotype is either () or (r) for round face, you will have a round face, because () is. 11) In order to figure out the possible genotypes of the offspring of two parents, scientists use a four box "graph" called a(n). 12) Each gene has two "forms", which can be either dominant or recessive. We represent each form with a letter. This letter is known as a(n). 17) Before endel, scientists thought that you look a little like your mother and a little lilke your father because of something called, which basically means a mixture of both. 19) In your cells there are 23 pairs of chromosomes. This mean that each chromosome in the pair is the same size and shape, and carries the same genes - one from om and one from Dad. 21) The process that occurs when pollen (male haploid sex cell) mixes with an egg (female haploid sex cell) to create a single diploid body cell is called. 25) Your phenotype (outward appearance) is controlled by your, which is your "genetic formula". This "formula" is represented by the two alleles you get from your om and Dad. 27) If you are a hybrid, which means you have a dominant and recessive allele for a particular trait, then you would be called for that trait. 32) Body cells have two sets of chromosomes, so they are diploid. Sex cells have one set, so they are. 33) A relationship between two different numbers is know as a(n). For example, if a classroom had 18 brown-haired people and 12 blond-haired people, this would be written as 3:2 35) When a male gamete (sperm), which has a half set of chromosomes, and a female gamete (ovule) with a half set come together during fertilization, the single cell create will have a complete set. This single cell is known as a(n). 36) Body cells are all the cells in your body that are not sex cells. These cells are also called cells. 40) The male part of the flower that produces pollen (anther) is connected to the rest of the flower by a long stem called the. 41) The man credited with being the father of genetics and heredity was regor. 43) If () is dominant for round face, then (r) would be for the same trait. 48) An abbreviation for enetic Crossover
