A. How many plants in F1 will be heterozygous.
In the crosses of 2 homozygous pea plants with smooth and wrinkled seeds in the F1 plants produced 8. All of them produced autogamy and gave in the F2 824 grains.
D. How many low plants would be in the Fb.
A. How many types of gametes form a heterozygous plant
In pea tall growth dominates above low growth. With the return crossing heterozygous tall plants with low received 98 plants.
In tomato gene conditioning red color of fruits dominates the genome of the yellow color of them. What are the colors of the fruit will be in plants obtained by crossing homozygous red fruit plants with yellow fruit. What fruits are in F2? List all forms of what can happen from the crossing of red-representatives F2 with F1? What can you get from crossing of both yellow representatives F2?
In the crossing of 2 pea plants with red flowers 14 plants with red and 5 with white flowers is received. What are the genotypes of parent plants?
Curly-haired father (his mother is curly-haired, and his father is sleek-haired) and sleek-haired mother's first child is curly-haired. What kind of hair will have their next children?
Tasks
B. How many types of gametes forms a low growing plant.
C. How many different genotypes would be in Fb.
C. How many wrinkled seeds will be in F2.
Laboratory work №3
Subject: Rules of experiment execution: the management of experiments protocol, preparation of a working hypothesis, interbreeding scheme, the construction of the conclusions. Working with the fruit fly - the main object of the laws of inheritance and variability of symptoms. Of experiments with mono-and dihybrid interbreeding.
Objective: To get acquainted with the rules of experiment design. Experiments with peas.
