Part 2: codominance - predicting stripe color in lizard tails a certain species of lizard can have red stripes, yellow stripes, or red and oranges stripes. an rr lizard has red stripes, an yy lizard has orange stripes, and an ry lizard has red and orange stripes. a lizard with red stripes(rr) mates with a lizard with orange stripes(yy). 3. create a punnett square to show their offspring, the f1 generation. punnett square parent r r y rr ry y yy ry 4. what pattern do you notice in the genotypes of the f1 generation lizards? 5. what are the phenotypes of the f1 generation lizards?

Which of the following sex and generation combinations directly produces the pollen tube of angiosperms? a) male gametophyteb) female gametophytec) male sporophyted) female sporophyte

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. assume all are homozygous. agouti x albino a) 1/2 albino, 1/2 agouti b) all agouti c) 3/4 agouti, 1/4 albino
