Warm Up n The physical appearance of an organism. n A section of DNA that contains the instructions for making a specific protein. n An organism that is heterozygous for a trait. n Choosing organisms with the desired traits for the offspring in the next generation. n Describes a trait/allele that is covered over— seems to disappear.
Warm Up n In a Punnett square, a capital letter stands for a ________ allele. n Who is known as the Father of Genetics. n A Punnett Square shows all the ways __________ can combine. n If Tall (T) is dominant over short (t) in pea plants, which of the following genotypes. n Draw and label a chromosome.
Warm Up n Explain why more boys are affected by sex- linked traits than girls? n Which parent determines the sex of the offspring? Explain. n (C R ) is the allele for red flowers; (C W ) is the allele for white flowers. n A heterozygous plant has pink flowers. n Use the Punnett square to show what genotypes you would get if you crossed two pink flowered parent plants?
