| show | Monohybrid cross is cross involving a single trait e.g flower color.... Dihybrid cross a cross involving two traits, e.g flower color and plant height
🗑
|

| What is used to solve genetic crosses? | show 🗑
|
||||
| show | Alleles-two forms of a gene (dominant and recessive)
🗑
|
||||
| Explain the difference between dominant and recessive alleles | show 🗑
|
||||
| show | Dominant (R), Recessive (r)
🗑
|
||||
| show | Allele combination for a trait (RR,Rr,rr)
🗑
|
||||
| show | The physical feature resulting from a genotype (red, white)
🗑
|
||||
| show | R= red flower RR,Rr,rr Red, Red, Yellow
r= yellow flower
🗑
|
||||
| show | Homozygous genotype are gene combination involving 2 dominant or 2 recessive alleles (RR or rr) also called pure
🗑
|
||||
| show | RR, rr
🗑
|
||||
| show | Rr
🗑
|
||||
| show | gene combination of one dominant and one recessive
🗑
|
||||
| Heterozygous genotypes are also called ...? | show 🗑
|
||||
| show | Genotype and phenotype
🗑
|
||||
| show | Small area needed, produce lots of offspring, produce pure plants when allowed to self-pollinate several generations
🗑
|
||||
| show | Female; ovary pollen carries sperm to the eggs for fertilization, male; stamen
🗑
|
||||
| show | Self; same flower
cross; different flowers
🗑
|
||||
| show | Mendel hand-pollinated flowers using a paint brush, He could snip the stamens to prevent self-pollination... covered each flower with a cloth bag,
🗑
|
||||
| show | He traced traits through several generations, pure strains by allowing the plants to self-pollinate for several generations
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
