Which of the follow are correct about the cells that come together to form a new cow?
The female cattle contributes the egg cell.
The egg cell has the same number of chromosomes as adult body cell.
The male cattle contributes the sperm cells.
The actin and myosin for the new cow are in the cells from the parents.
The sperm cell has the same number of chromosomes an adult body cell.
What do we call different versions of the chromosome at a specific location on the chromosome?
a gene
an allele
a receptor
a phenotype
Which are true about typical-muscle cattle parents and their offspring. (Choose one or more answers.)
Sperm and egg both show an allele related to typical myostatin (each has a circle symbol).
Sperm and egg both show an allele related to partial myostatin (each has a star symbol).
Offspring's cell shows both alleles for typical myostatin (two circle symbols).
Offspring's cell shows both alleles for partial myostatin (two star symbols).
Which are true about the genotype of the cattle and the myostatin proteins and level of muscles it produces?
The genotype of the cattle myostatin is made of two alleles.
The cattle's
genotype
determines the
shape of the myostatin proteins
it makes.
The
shape of the myostatin
protein determines the
muscle phenotype
of the cattle.
Which of the following is the phenotype of an extra-muscled cattle?
The type or version of the myostatin.
A description of the allele on a specific gene.
The chart that shows all 30 pairs of chromosomes in the cattle's muscle cells.
Visually noticeable extra large muscles.
Why is myostatin important to growing muscles in cattle?
A. Muscle fiber are made of myostatin proteins.
B. The myostatin protein controls which alleles are on the chromosome which controls muscle growth.
C. The myostatin protein's shape connect to a receptor on muscles cells and controls its growth.
D. The myostatin protein is not important to growing muscles in cattle.

Extra Muscle
According to the key, what type of muscle does the individual in the bottom row (square) have?
Typical Muscle
Medium Muscle
Extra Muscle
Which of the following statements are true about the cattle family trees?
The grandparents phenotype in cattle families A and B is medium muscle.
In Family B, the offspring is female.
In Family A, the offspring is male.
In cattle family trees A and B, it is evident that offspring inherit traits similar to those of their parents.
Consider the following scenario and complete the organizer below.
Scenario:
Imagine the offspring of cattle families A and B grew up and had their own offspring (see Family C on the info sheet).
What possible genotype(s) and phenotype(s) could the new parents pass on to the baby?
Which of the following best describes the possible genotype(s) and phenotype(s) that the new parents could pass on to their baby?
Genotype: Circle, Circle
Phenotype: Extra Bog Muscle
Genotype: Star, Circle
Phenotype: Medium Muscle
Genotype: Star, Star
