XY, XY
Which part of the backbone of a DNA strand do the bases connect to?
both parts
sugar
phosphate
neither part
What is the definition of heterozygous?
Having 2 of the same alleles
Having 2 different alleles
Having both dominate alleles
Knowing how to pronounce alleles correctly
Using Mendel's Pea Plant guide answer this question. If both parents are purple but carry the white flower allele, what possible outcome can their offspring have? Use a Punnett Square to support your answer.
1 purple, 2 lilac, 1 white
2 homozygous and 2 heterozygous
4 purple and 0 white
4 heterozygous

23 pairs
23
46
2 pairs

sugar and salt
sugar and phosphate
salt and pepper
sugar and photosynthesis
Alleles are
always longer than each other and work together
always come in pairs and are either dominant or recessive
never longer than each other and don't work together
never come in pairs and are the same
What is the definition of homozygous?
Having 2 different alleles
Having 2 of the same alleles
Knowing how to pronounce alleles correctly
Having both dominate alleles
What did Gregor Mendel study to learn about genetics?

(a)
Using Mendel's Pea Plant guide answer this question. If both parents were purple how is it possible to have a white offspring?
(a)
A husband and a wife have three children, all boys. The mother is about to give birth to their fourth child. What are the odds that the child will be a girl? Use a Punnett Square to support your answer.
75% boy, 25% girl
50% boy, 50% girl
25% boy, 75% girl
100% girl because there are 4 squares and they have 3 boys so it has to be a girl
